The DRV8363-Q1 implements Bootstrap Undervoltage, GVDD Undervoltage, VDS and VGS monitoring, and Thermal Shutdown in case of overtemperature. See the DRV8363-Q1 data sheet for more information on DRV8363-Q1 fault support.

Status LEDs for the 3.3V, 5V, PVDD, GVDD, and FAULT are included and shown below.

The FAULT LED lights up if the EVM senses a fault and the same fault is reported in the SPI register. See the complete data sheet for fault response and corrective actions.

The nFAULT LED lights up when the board is powered, until logic high is applied to nSLEEP pin.

The Faults can be reset in the GUI software using the CLEAR FAULTS button. More details on the GUI can be found in Section 3.

The EVM includes a buck regulator for reducing VMOTOR to 12V in case regulation is required. The buck feeds into the 3.3V LDO and 5V LDO, which powers the EVM 3.3V and 5V rails.

Jumper J6 connects VMOTOR to the buck (default). Remove this jumper if you want to power down the buck regulator.

Jumper J7 connects the PVDD buck output (12V) to the 3.3V LDO (default). Remove this jumper if you want to power down the 3.3V rail.

Jumper J15 connects the PVDD buck output (12V) to the 5V LDO (default). Remove this jumper if you want to power down the 5V rail.

GVDD is powered by the buck output (12V) by default, but can configured for external supply support by placing J1 shunt on pins 1:2 as shown.
