Working Principles

MC33932VWR2 operates by receiving input signals (INA, INB) to control the direction of the motor. The integrated circuit generates gate drive voltages using a charge pump (VCP) and regulates the logic supply voltage (VDD). It monitors the motor current through the sense voltage (VS) and provides overcurrent protection by triggering the fault output (FLT) when the current exceeds the set limit. In case of excessive temperature, the thermal shutdown protection activates, ensuring the safety of the motor and the IC.
