Reference Design Board , STSPIN32F0252, 3 Phase BLDC Motor Controller

STEVAL-PTOOL2V1 BLDC driver reference design is tailored for battery-operated power tools using 8S to 15S battery packs. It is based on the STSPIN32F0252 motor controller with embedded 3-phase, 250 V gate driver and low-power STM32 MCU. The power stage is based on the STL130N8F7 power MOSFETs or any similarly rated device in a PowerFlat 5x6 package. The board implements single shunt sensing topology with both field-oriented control (FOC) and sensored or sensorless 6-step control supported for driving permanent magnet synchronous motors (PMSM) and brushless DC (BLDC) motors. The companion 6-step STSW-PTOOL2V1 firmware is ready to use with position feedback from phase Hall-effect sensors.
