IntroductionThe STEVAL-SPIN3204 three-phase brushless DC motor driver board is based on the STSPIN32F0B 3-phase BLDC controllerwith triple half-bridge gate driver, single shunt resistor current sensing topology and programmable overcurrent protection.

The motor controller system-in-package includes an STM32F031C6 microcontroller ready to execute 6-step, field orientedcontrol (FOC) and other advanced driving algorithms in the firmware, which can be downloaded onto the chip flash memory viathe board USB port.

The board is designed to help you test and develop motor control designs for applications such as power tools, homeappliances, fans and pumps, with a flexible evaluation platform that even allows you to toggle between external sensor andsensorless position feedback data methods.

The power stage on the board delivers 15 ARMS DC current from three STD140N6F7 MOSFETs in half-bridgeconfiguration managed by the triple half-bridge gate driver on the BLDC controller.The board senses the current flowing into the motor phases through a shunt resistor, and the resulting signal isamplified, filtered and forwarded to the STSPIN32F0B BLDC controller MCU and control logic gate driver formonitoring and peak current limitation or overcurrent protection, depending on the driving method implemented inthe firmware (voltage mode or current mode, respectively). Voltage sensing is implemented through a voltagedivider from the motor supply voltage (VBUS) and sent to the BLDC controller MCU for monitoring purposes.The board also features an embedded ST-LINK/V2-1 programmer/debugger to help you load, test and modify themotor controller firmware.

1.3 STSPIN32F0B advanced single shunt BLDC controller with embedded STM32MCU

1.3.1 BLDC motor controller descriptionThe STSPIN32F0B is a System-In-Package providing an integrated solution suitable for driving three-phasebrushless motors using different driving modes.It embeds a triple half-bridge gate driver able to drive power MOSFETs with a current capability of 600 mA (sinkand source). The high- and low-side switches of same half-bridge cannot be simultaneously driven high thanks toan integrated interlocking function.An internal DC/DC buck converter provides the 3.3 V voltage suitable to supply both the MCU and externalcomponents. An internal LDO linear regulator provides the supply voltage for gate drivers.The integrated operational amplifier is available for the signal conditioning, e.g. the current sensing across theshunt resistor.A comparator with a programmable threshold is integrated to perform the overcurrent protection.The integrated MCU (STM32F031C6 with extended temperature range, suffix 7 version) allows performing field-oriented control, the 6-step sensorless and other advanced driving algorithms. It has the write-protection andread-protection feature for the embedded Flash memory to protect against unwanted writing and/or reading. It ispossible to download the firmware on-the-field through the serial interface thanks to the embedded bootloader.The STSPIN32F0B device also features overtemperature and undervoltage lockout protections and can be put inthe standby mode to reduce the power consumption. The device provides 20 general-purpose I/O ports (GPIO)with the 5 V tolerant capability, one 12-bit analog-to-digital converter with up to 9 channels performingconversions in a single-shot or scan modes, 5 synchronizable general-purpose timers and supports an easy touse debugging serial interface (SWD).

1.4 Overcurrent protectionWhen the jumper J11 is closed in the 1-2 position, the board is set to use the current sensing for implementing theovercurrent protection.Load current is forwarded to comparator input according to following formula:VOCCOMP = Iload × Rsℎunt × GOPAMP = Iload × 10mΩ × 3.125 (1)

Table 1. Overcurrent thresholds

PF6 PF7 Internal comp. threshold OC threshold

0 1 100 mV 3.2 A

1 0 250 mV 8 A

1 1 500 mV 16 A

The protection can be implemented in one of the following ways:• Using the protection circuitry integrated in the analog section of the STSPIN32F0B SiP; this feature is

enabled by setting the OC_SEL input (PA11) high.• Using the TIM1_BKIN input.

UM2572Overcurrent protection

UM2572 - Rev 1 page 6/23

1.5 Current mode driving (current limiter)When the jumper J11 is closed in the 2-3 position, the board is set to use the current sensing to implement anadjustable current limiter.The target of the current limiter depends on the duty-cycle (DC) of the PWM on PA6 GPIO and the comparatorinternal comparator threshold (VOCCOMPth):Ilimit = VOCCOMPtℎ− VDD × DC × GREFRsℎunt × GOPAMP = VOCCOMPtℎ− 3.3V × DC × 0.15610mΩ × 3.125 (2)

The VOCCOMPth is set through the PF6 and PF7 GPIOs of the embedded MCU.

1.6 Hall effect sensors and Quadrature encoderThe STEVAL-SPIN3204 evaluation board supports digital Hall sensors and quadrature encoder motor positionfeedback. The sensors can be connected to the STSPIN32F0B by closing jumpers JP5, JP6 and JP7.

Note: When JP5, JP6 and JP7 for Hall/encoder sensing are closed, ensure that JP8, JP9 and JP10 for BEMF sensingare open.The Hall sensors/encoder should be connected to J4 as shown in the following table.

A protection series resistor of 1 kΩ is mounted in series with connector inputs.For sensors requiring an external pull-up, three 10 kΩ resistors are already mounted on the output lines andconnected to the VDD voltage. On the same lines, a footprint for pull-down resistors is also available (R59, R60and R61).The jumper JP3 selects the supply line for the sensor:• Jumper between 1-2 pins: sensors powered by VUSB (5 V)• Jumper between 2-3 pins: sensors powered by VDD (3.3 V)

1.7 Programming and debugging the STSPIN32F0B motor controllerThe STEVAL-SPIN3204 evaluation board embeds an ST-LINK/V2-1 debugger/programmer, with the followingfeatures:• USB software re-enumeration• Virtual com port interface on USB connected to PB6/PB7 pins of the STSPIN32F0B (UART1)• Mass storage interface on USB

The power supply for the ST-LINK is provided by the host PC through the USB cable connected to the board.The red-green LED LD1 provides the following ST-LINK communication status information:• Red LED flashing slowly: at power-on before USB initialization• Red LED flashing quickly: following first correct communication between the PC and ST-LINK/V2-1

(enumeration)• Red LED ON: initialization between the PC and ST-LINK/V2-1 is complete• Green LED ON: successful target communication initialization• Red/green LED flashing: during communication with target• Green ON: communication finished and successful.

The reset function is disconnected from the ST-LINK by removing the jumper J8.
