  • DRV8316REVM: Going to SLEEP after OC fault Bug

    TI Thinks Resolved
    Part Number: DRV8316REVM Hello, I was testing latched OCP mode and I found this weird issue. After an OCP occurs, nFAULT goes low and FETs are HI-z as expected. However in this state, if nSLEEP is driven low, the FETs look like they open momentarily: …
