8.4.1.3 Fault Reset (ENABLE Reset Pulse)

In the case of device-latched faults, the DRV8306 device goes to driver Hi-Z state to help protect the external power MOSFETs and system.

When the fault condition is removed the device can go back to the operating state by issuing a result pulse to the ENABLE pin on either interface variant. The ENABLE reset pulse (tRST) consists of a high-to-low-to-high transition on the ENABLE pin. The low period of the sequence should fall with the tRST time window or else the device will begin the complete shutdown sequence. The reset pulse has no effect on any of the regulators, device settings, or other functional blocks
