Features• Input voltage from 7 to 45 V• Output current up to 15 ARMS

• Power stage based on STD140N6F7 MOSFET• Embedded 3.3 V buck regulator• Embedded 12 V LDO regulator• Single shunt current sensing• Digital Hall sensors and encoder input• Overcurrent comparator• Bus voltage sensing• Embedded ST-LINK/V2-1• Easy user interface with buttons and trimmer• RoHS and WEEE compliant

Applications• Battery powered power tools• Home appliances• Pumps and fans• Industrial automation

DescriptionThe STEVAL-SPIN3204 three-phase brushless DC motor driver board is based onthe STSPIN32F0B 3-phase BLDC controller with triple half-bridge gate driver, singleshunt resistor current sensing topology and programmable overcurrent protection.

The motor controller system-in-package includes an STM32F031C6 microcontrollerready to execute 6-step, field oriented control (FOC) and other advanced drivingalgorithms 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 forapplications such as power tools, home appliances, fans and pumps, with a flexibleevaluation platform that even allows you to toggle between external sensor andsensorless position feedback data methods.

1 Solution overview

The STEVAL-SPIN3204 motor control board can be set up to control a three-phase brushless DC (BLDC) motorbased on position feedback data from one of the following sources:• external quadrature encoders or Hall Effect sensors• on-board circuitry that senses the back electromotive force (BEMF) generated by the load motor.

on STM32 MCSDK

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 signalis amplified, 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 implementedin the 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.
