Introduction

Maxim Integrated has been a supplier of quality devices to the military/aerospace community for over 25 years. Maxim is an approved supplier to virtually all the world’s leading military and aerospace OEMs and is also on the preferred vendor list at many of these same manufacturers.

With this product guide and our updated web pages, we are continuing our efforts to become more visible to the entire breadth of the military and aerospace community. In this product guide, you will find a brief overview of a few of Maxim’s more than 10,000 parts with suggestions for some possible applications.

Before you dive into the details of each device, we encourage you to review the first few pages of this guide. On these pages, we cover three exclusive Maxim programs targeted at solving the biggest problems facing the military/aerospace OEMs today:

• Device obsolescence • We solve the problem where you “run out of parts before you run out of program.”

• Lead (SnPb) finish • We can offer a SnPb finish for virtually any Maxim part—just ask!

• Full military temperature range • We have a program to characterize non-military temperature parts for military temperature

applications—called Ruggedized Plastic.

As you peruse the pages of this guide, note that for every component listed we have dozens more. If you do not see a solution to your problem, just ask us. We are constantly innovating new solutions—a new part every day!

Sincerely,

John O’Boyle Senior Manager, Military Aerospace Group

Obsolescence Mitigation ProgramCOTS Parts for Long-Life ProgramsThe move by military primes to commercial-off-the-shelf (COTS) parts has brought the expected benefit of lower cost to finished assemblies. However, accompanying that has been the early obsolescence of the COTS parts themselves. An unintended consequence of the cost-containment move is that the prime will run out of the industrial-grade part before he runs out of program. To address this situation, Maxim’s Mil/Aero group has designed a special program for primes or any customer with long-life programs using Maxim plastic parts. When the Maxim part is announced as a last-time buy (LTB), the prime/customer can do one of the following three options:• Redesign the impacted board

• Costly, since redesign is expensive• Purchase sufficient devices in LTB for expected program duration

• Risky, due to possible large cash outlay and need for special long-term, moisture-free storage of parts • Uncertain, because program may not remain in force for projected duration, or may go longer

• Contact Maxim’s Mil/Aero group for the obsolescence mitigation (OM) program described below (recommended)When the customer discovers that a Maxim part on their BOM is being made obsolete, they should contact Maxim’s Mil/Aero group to discuss the OM program. Maxim posts obsolescence notices with DLA and with GIDEP. Maxim and our distributor AVNET also notify customers that have purchased a given part within the past two years.

Parameters• Any Maxim plastic part, leaded or lead-free, any temperature range• Not limited to military-only parts

Procedure1. The customer and Maxim’s Mil/Aero group collaborate on the needs and terms2. Dialogue must commence BEFORE the LTB date to ensure that the Mil/Aero group can secure wafers3. Customer defines the length of program in years and the quantity needed for the remaining life of the program4. Maxim’s Mil/Aero group calculates the number of wafers needed to support this requirement5. Customer places order for first-year demand

• First-year demand is defined as the total life quantity divided by the number of years • Maxim builds first-year demand • Maxim sets aside remaining required wafers plus sufficient extra wafers for possible program extension or increase in

annual demand (Note: Parts are set aside ONLY after first order)6. Set-aside wafers held for single customer only; no one else, even from the same firm, can have access7. Minimum order quantity (MOQ) for any given buy is 500 pieces8. No obligation to order after initial purchase9. Customer can place order for any quantity (MOQ = 500) in years two through n

• If customer cancels program, Maxim closes out storage and scraps wafers at no extra charge to customer

Customer Benefits• Design in a Maxim part knowing that, if it becomes obsolete during the life of the program, the customer can work with

Maxim’s Mil/Aero group to ensure a supply for life• Future-built parts will have then-current date codes

• LTB parts all have the same date code; OM program parts built in the future will have future date codes • No storage charge for wafers

Lead-Finish ProgramMaxim’s Mil/Aero group offers two lead (SnPb)-finish options to customers who require lead-finished products instead of the standard RoHS-compliant (lead-free) COTS parts. These special programs, one for low volumes and another for high volumes, apply to virtually any Maxim COTS plastic part.*

Hot-Solder Dip for Low Volumes• Take lead-free parts from inventory

• Must have inventory for this to happen• Remove pure tin finish and replace with 63/37 SnPb solder

• XRF to make sure no pure tin remains; XRF report available• Parts marked with orange color (dot) per GEIA-STD-0006• 100% electrical test with original Maxim QCI test program• Maxim warranty applies• MOQ = 50• Typical lead time is approximately 6 weeks (±2 weeks)• Particularly suited for spares and prototyping

Lead Electroplate for High Volumes• Designed for applications that require a lead-finished part in higher volumes• Take wafer from production line or wafer stores

• Must have inventory or work in progress for this to happen• Manufacture on conventional lead (SnPb) manufacturing flow

• Same way parts were built before RoHS initiative• 100% electrical test with Maxim QCI test program• Maxim warranty applies• MOQ is a function of the number of die on a wafer• Lead time is a function of wafer inventory

www.maximintegrated.com/lead-finish

*Some devices cannot be finished in lead. In addition, a small number of devices cannot be hot-solder dipped because they are physically too small and may crack during processing. Preprocessing only supports lead-free production. For more information, contact Maxim's Military Business Manager at www.maximintegrated.com/lead-finish.

Ruggedized Plastic Parts for Mil/Aero ApplicationsMaxim offers ruggedized plastic-packaged ICs for stressful, high-reliability military and aerospace applications where moisture resistance is not an issue. A “ruggedized” product is one that has been burned-in and tested to military specifications. Usually, ruggedized products are packaged in hermetic packages. However, some military and aerospace applications do not require the expense of a full hermetic package, but do require high-reliability processing. For such applications, Maxim’s ruggedized military plastic products fulfill this processing requirement and can be thought of as super-COTS products. All of Maxim’s ruggedized plastic parts ship with a Certificate of Compliance, just as the full military specified hermetic devices do.Realizing that many military customers do board-level burn-in and temperature cycling, Maxim offers our ruggedized plastic in various configurations to meet your needs.

V62-• DLA-controlled, enhanced-temperature, lead (SnPb)-finished plastic-packaged devices

• Also called Vendor Item Drawing

/PR• 100% burn-in at +135°C for 120 hours

• Virtually eliminates all infant mortality issues• 100% tri-temp tested over the entire military temperature range to assure the industry's highest possible reliability in a plastic-

packaged device • The actual device received by the customer has been proven to operate over the full military temperature range

/PR2• No burn-in

• Appropriate for customers that do their own board or system-level burn-in• 100% tri-temp tested over the entire military temperature range to assure highest possible reliability in a plastic-packaged

device • The actual device received by the customer has been proven to operate over the full military temperature range

/PR3• No burn-in or tri-temp testing

• Appropriate for customers doing their own system-level burn-in and tri-temp testing • Devices are tested to more stringent limits to guarantee performance over temperature

The standard lead finish for all three /PR options is 85/15 SnPb electroplating, which eliminates tin whiskers as well as potential (lead-free) solder cracking in the field, especially in high vibration environments.The ruggedized plastic parts are ideal for airborne and other stressful high-reliability applications where moisture resistance is not an issue. Maxim presently offers over 100 specialized ruggedized plastic parts, with more parts continually being added.

Stingy on Power, Small in Size, High in Efficiency1-Cell Li+ Battery-Pack Chargers for Automatic Adapter Detection and USB Enumeration—Ideal for Military ApplicationsThe MAX8895 USB-compliant linear battery charger family offers devices that operate from either a USB port or a dedicated charger with automatic detection of adapter type and USB enumeration capability. The MAX8895 easily handles switchover from adapter and USB to battery power. It allows the system to utilize all available input power when necessary. This enables immediate operation with a dead or missing battery when power is applied.

• Determine the best use of available input power without needing a system to evaluate the power source; needs no microcontroller or system software

• No need for external diodes or MOSFETs• Reduce die temperature with thermal regulation loop

• Distinguish between adapter types • DCP: 500mA to 1.5A • CDP (host or hub): to 900mA (580mA during chirp) for Hi-Speed USB; to 1.5A for low and fast speed • Low-power SDP (host or hub): 100mA • High-power SDP (host or hub): 500mA

Broad Range of Li+ Battery Chargers

Simple, Safe, Small Li+ Battery Chargers Efficiently Manage Your Power PathA primary function in portable military devices is to charge the battery quickly, while optimally controlling the battery current and voltage based on charging requirements for the specific battery chemistry. This is especially true when deployed in a rugged battlefield environment. When USB power or an AC adapter is connected to the device, a smart battery charger should allow the device to turn on instantly, even if the battery is completely depleted. The charger should also make the best use of limited USB or adapter power and charge the battery with additional input power not used by the system. Additionally, the system load needs to switch from the battery to the external input power source when external input power is available. Maxim offers a wide selection of battery chargers that fulfill these requirements.

Maxim's Smart Power Selector Circuitry Enables Efficient Power DistributionMaxim’s latest battery monitors efficiently distribute power through Maxim’s proprietary Smart Power Selector circuitry. When external power is connected, Smart Power Selector circuitry allows the system to operate with no battery or a deeply discharged battery. It automatically switches the system load from the battery and makes the best use of limited USB or adapter power, while charging the battery from input power not used by the system. All necessary power switches and current-sense circuitry are included on the chip, thus providing a complete, highly integrated solution for battery monitoring in devices for which energy efficiency is vital.

Single-Chip PMICs Reduce Cost and Size for 1-Cell Li+ Battery-Powered ProductsUp to 95% Efficient DC-DC Converters and Low 1.7V (min) Input-Voltage LDOs Maximize Battery LifeThe highly integrated MAX8662/MAX8663 power-management ICs (PMICs) are cost-effective, small-footprint complete solutions for today’s powered soldier. They are ideal for use in night vision systems, head-mounted displays, GPS devices, and communications. These PMICs optimize system performance, cost, and size with two high-efficiency step-down DC-DC converters, four LDOs, one step-up DC-DC converter for WLEDs/OLEDs, and a lithium-ion (Li+) charger in a single IC.

RS-232 Transceivers Allow Communication with Military Legacy DevicesMaxim was a pioneer in the interface field with the first RS-232 transceivers in 1987. We continue that legacy today, supporting these early designs while also introducing current state-of-the-art devices. Though most were designed many years ago, our RS-232 transceivers still find application where robustness and ease of use are imperative, such as in military devices. Below are a few of the literally hundreds of different transceivers available, offering everything from AutoShutdown™ for enhanced battery life to advanced data rates up to 1Mbps.

Extremely Accurate RTCs

If It's Electronic, It Needs a ClockUnprecedented Timekeeping Accuracy from < ±5ppm Down to < ±2ppmMaxim’s accurate real-time clocks (RTCs) maintain precise time across a broad temperature range (from -40°C to +85°C). A variety of products with the newest technology innovations are available, such as a MEMs-based accurate RTC that provides enhanced reliability and ruggedness as well as less susceptibility to aging, EMI, and vibration. This RTC provides low-current operation and accuracy comparable to crystal-based solutions.

Maxim’s accurate timekeeping products are designed to provide improved performance over a standard tuning-fork crystal. By nature, crystals have frequency variations due to changes in ambient temperature. Over the -40°C to +85°C temperature range, the frequency of a crystal can deviate by 100s of parts per million. This results in time inaccuracies of hours per year. In contrast, Maxim’s accurate RTCs provide accuracies as good as 2 minutes per year.

With several devices to choose from, users needing accurate timekeeping are provided a variety of interface options, memory options, and package sizes ranging from the 300 mil, 20-pin SO down to the tiny 150 mil, 8-pin SO (DS3231MZ+). Each device is individually calibrated across its specified temperature range and guaranteed accurate to data sheet specifications. All devices are designed to support battery-backed operation and operate in low-current modes when supplied power through the VBAT terminal. They are also RoHS compatible, and the DS3231M device is fully RoHS compliant.

If It's Electronic, It Needs a Clock (cont.)

Military and aerospace applications such as maintenance scheduling, metering, equipment scheduling and management, security, access control, and vehicle maintenance (including UAVs) are finding accurate timekeeping essential to the operation and up-time of the end equipment. Whether accurate timekeeping is used for manpower scheduling purposes, time-stamping of critical event transactions, or aiding in satellite capture for GPS applications, accurate RTCs provide the most suitable and cost-effective method for implementing accuracy in end equipment.

Featured Discussion: Microprocessor SupervisorsMicroprocessor-Reset ICsMicroprocessors require a reset pulse during power-up to initialize the internal registers and prevent unwanted code execution. Without a reset, the device could attempt to run even when the clock oscillator or VCC has not stabilized, thereby causing unpredictable operation.

The circuit below shows an inexpensive way to add a reset function to a microprocessor that needs an active-low reset signal. Although low cost, the circuit has limitations—namely, inaccurate voltage and timing specifications.

Integrated reset circuits combine an accurate voltage monitor with precise timing circuitry to solve the problems associated with discrete circuits. These ICs should be used when an application requires the system voltage to fall within narrow tolerances before operating normally, or when a delay is needed to allow the clock oscillator to start up.Maxim offers the industry’s widest range of microprocessor-reset circuits. These circuits include multiple reset-output types, precision reset thresholds, threshold hysteresis, and accurate reset timeouts. Maxim's reset ICs also integrate functions such as a manual-reset (MR) input, watchdog timer, and an additional comparator input and output. Devices such as the MAX16072−MAX16074 squeeze these features into an ultra-small, 1mm x 1mm, chip-scale package. These reset ICs are perfect for applications with limited board space.

Discrete implementations are plagued by inaccurate voltage and

timing specifications.

Maxim's reset ICs integrate an accurate voltage monitor and

precise timing circuitry.

Point-of-Load Regulators Provide Protection for FPGAs in Mil/Aero ApplicationsHigh-performance/high-power FPGAs are often deployed in military and aerospace applications. They typically are built on plug-in cards powered by a 48V backplane. A two-stage distributed power architecture (DPA) is often used in these applications for the individual cards, the first stage being a step-down converter that converts the 48V to an isolated intermediate voltage such as 12V or 5V. This voltage is then further downconverted to the required voltages for the FPGA in the point-of-load (POL) regulators.

High-Performance Regulators with High Reliability Over a Wide Operating RangeMaxim’s family of high-performance regulators operates over a very wide input voltage range (up to 72V) and tolerates many voltage transients without any external circuitry. The ICs are fully specified up to +125°C and can dissipate more power than most competitive solutions. They also integrate various features such as a reset output, an extra undedicated comparator (PFI/PFO), a watchdog timer, enable and hold functionality, and a gate driver (GATEP) that protects against reverse-battery conditions by using a pFET.

Overvoltage Protectors Prevent Damage to Downstream Critical CircuitryMaxim’s overvoltage protectors can protect military and aerospace designed circuits from transient voltages up to 72V, overvoltages, or reverse-voltage conditions.These devices use series-pass MOSFETs to instantly disconnect the circuit during a fault condition. After the fault condition is resolved, the MOSFETs turn back on so that the circuit can continue to operate.

Video Decoders for Low-Cost, Reliable, Advanced UAS/UCAV Vision Systems

Video decoders are critical in determining the level of video quality available for further processing downstream. Until now, designers of cost-sensitive applications have frequently had to settle for 9-bit, 2x oversampling decoders that offer inferior video quality. This performance-cost tradeoff has impeded the transition from analog systems to digital video solutions in some industries and markets. However, Maxim’s codecs provide superb video quality at a competitive price, effectively eliminating the need to sacrifice video quality for cost.
