Top Market Worldwide ShareOur voltage detectors IC are used in a wide variety of applications consumer, industrial a testament to their high quality and reliability

Broad Line-upOur wide line-up includes units capable of voltage detection from as low as0.9V and models compatible with the latest 1.0V drive of microcontrollers

High Reliability, Wide Temperature range8KV ESD resistance ensures high reliability, 40C up to +125C(+105C)

High Accuracy, Low Power Consumption & Small Thin Packages

The ROHM voltage detector IC series are reset IC with- highly accurate detection voltage of1%- low current consumption- small thin packages (VSOF5, SSOP5, SOP4) Default SSOP packages

are pin-compatible and function-compatible, so they can be used asreplacement for existing IC

In-House Manufacturing

The entire manufacturing process from wafer fabrication to assembly andshipment is entirely performed in-house, resulting in an unmatched levelof quality

Low Environment FriendlyAll of our products are both lead-free and RoHS compliant, reducing burdenon the environment

Voltage Detector Function Example

4.2V

Detection Voltage is defined by the transition:

VDD: H L

Example:BD4842 VDET (typ) = 4.2V

1% accuracy VDET (min) = 0.99

x 4.2V = 4.158VVDET (max)= 1.01 x 4.2V

= 4.242V
