CAUTION
High-voltage levels are present on the evaluation module whenever it is energized. Take proper
precautions when working with the EVM.
2.1.1 FAULT and OC
The FAULT and OC pins of the LMG342XEVM-04X are active low when an undervoltage lockout occurs on an
auxiliary voltage rail, when an overtemperature event occurs, or when an overcurrent/short-circuit event occurs
on the LMG342XR0X0. The signals are level-shifted to AGND. Refer to the LMG342XR0X0 data sheet for
operation details.
