No protective action occurs after a SEN_OCP event in this mode. The overcurrent event is reported by driving the nFAULT pin low and latching the FAULT and SEN_OCP bits high in the SPI registers. The gate drivers continue to operate. The external controller manages the overcurrent condition by acting appropriately. The reporting clears (nFAULT released) when the SEN_OCP condition is removed and a clear faults command is issued either through the CLR_FLT bit or an ENABLE reset pulse (tRST).
