LMG342X-BB-EVM: Device not working; Random Fault LEDs light up with auxiliary supply and without any PWM Signal or HV input

Part Number: LMG342X-BB-EVM
Other Parts Discussed in Thread: LMG34XX-BB-EVM


We are in the process of testing new LMG342x-BB-EVM board with LMG3422EVM-043.

The issue with the board is, as soon as 12 V auxiliary power is applied to J6, some random FAULT LEDs light up. I say randomly because, not necessarily the same LED will it up always the 12 V power is supplied. Primarily the HS_OC LED (Yellow)  lights up or sometimes, pair of HS_OC and HS_FLT (RED) or a combination of HS_OC, HS_FLT and LS_FLT (RED) together.

What could be the reason for this issue? and to to resolve this?
