DRV8874-Q1: OCP Auto-Retry Mode

Part Number: DRV8874-Q1

Hello,

I was verifying the Auto-Retry mode on the OCP feature and I got these scope shots:

CH1: VM, CH2: IOUT, CH3: OUT1 CH4: nFAULT

The setup is using Auto-Retry OCP mode with an E-load trying to draw about 9A from OUT1 and OUT2 continuously.

Two issues:

1) Why is tretry around 100us in the first image

2) Why do the FETs not retry as soon as nFAULT asserts high again. There is a 486us delay between nFAULT assert high and FET conducting again
