The STEVAL-SPIN3202 evaluation board provides a complete single-shunt six-step solution consisting of an STSPIN32F0A (advanced BLDC controller with an embedded STM32 MCU) and a triple half-bridge power stage with the NMOS STD140N6F7.
The STSPIN32F0A autonomously generates all the required supply voltages starting from the motor supply: the internal DC/DC buck converter provides 3.3 V and the internal linear regulator provides 12 V for the gate drivers.
The current feedback signal conditioning is performed through the operational amplifiers embedded in the device and an internal comparator performs overcurrent protection via the shunt resistor.
Two user buttons, two LEDs and a trimmer are available to implement simple user interfaces (e.g., starting/stopping the motor and set target speed).
The STEVAL-SPIN3202 evaluation board supports the quadrature encoder and digital Hall sensors for motor position feedback. It also provides the circuitry to sense the motor BEMF (sensorless operation).
The board includes an ST-LINK-V2 which allows the user to debug and download firmware without any extra hardware.bThe board also supports sensored or sensorless Field Oriented Control algorithm with single-shunt sensing.
