STSPIN32G4 Motor Controller with STM32G4 MCU STMicroelectronics STSPIN32G4 Motor Controller with STM32G4 MCU is an extremely integrated and flexible motor controller for driving 3-phase brushless motors. This device helps designers choose the most suitable driving mode and reduce PCB area and the overall Bill Of Materials. The STSPIN32G4 embeds a triple half-bridge gate driver able to drive power MOSFETs with a current capability of 1A (sink and source). Three bootstrap diodes are embedded as well. The high and low-side switches of the same half-bridge cannot be simultaneously driven high, thanks to an integrated interlocking function. An additional protection feature is represented by hardware VDS monitoring circuitry that constantly monitors each of the six external MOSFETs. If an overvoltage is detected across one of them, it switches off all gate driver outputs. The overvoltage threshold is set through a dedicated SCREF pin.
