Power Supply Setup
A single power supply is required to power up the EVM. Because most of the pins are PVCC compliant, the PVCC supply also can be used to power the analog supply (AVCC) and can be used to pull up the logic pins for shutdown (SD) control and fault detection (FAULT). GVDD is an internally generated supply for the output FETs and also is used to power the PLIMIT voltage divider circuit on the EVM. PLIMIT is GVDD compliant, but not PVCC compliant. PLIMIT also can be powered by an external supply connected to the PLIMIT pin.
