2.6 Fault Detection

The LMG210XR022 indicates three kind of faults on the EN/FLT pin: short-circuit event on the low-side GaN FET, UVLO event on the VCC supply, and over-temperature event on the driver. Once asserted, the active low fault signal remains asserted as long any of the three faults exist, and the Fault LED D5 turns on indicating Fault.
