7.4.2 DRVOFF Functionality

MCT8376Z-Q1 has capability to disable predriver and MOSFETs through DRVOFF pin. When DRVOFF pin is pulled high, all six MOSFETs are disabled. If nSLEEP is high when the DRVOFF pin is high, the charge pump, AVDD regulator, GVDD regulator, and SPI bus are active and any driver-related faults such as OCP is inactive. DRVOFF pin independently disables MOSFETs which stops motor commutation irrespective of status of INHx and INLx input pins.
