Hi Dheeraj,

There are two comments:

1) The nFAULT pin of the DRV8803 is an open drain and should be connected to a pullup resistor.

2) The outputs of the DRV8803 are open drain. What the the outputs connected to?

DRV output is connected to outside relay module which are controller by 24V.

Hi Dheeraj,

If the DRV output is connecting the outside module to GND to complete the circuit, there are no further comments.

The DRV8803 is intended to be used in this application.
