Other Parts Discussed in Thread: BQ25750
I have a issue with the EVM dev board that having followed the datasheet, EVM user guide and checked voltages on the PCB however I am seeing the error flag "Device in under-voltage protection" Register 24h bit 7
Below is the register dump from Battery Management tool along with screen shots. And help would be great as I must be missing something?
