Hi,
We are using DRV8873S SPI Version in our own designed board.
We have connected the motor at H-Bridge OUT1 and OUT2 and simulating the OL condition in Passive mode, but we are getting the nFAULT pin status low (Multimeter reading=1V).
1. Why we are getting the nFAULT status low when the motor is connected?
2. We have followed the datasheet parameters for OL detection in passive mode.
3. The SPI registers values are:
IC1_CONFIG_DATA 0x0080u
IC2_CONFIG_DATA 0x00ADu
IC3_CONFIG_DATA 0x0030u
IC4_CONFIG_DATA 0x0040u
Can you suggest the possible reason for nFAULT status low, even when there is motor connected at the output of the Driver?
Regards
