Hello,
We are currently running into an issue where our charger ICs seem to be failing.
The chargers are initially working/charging fine.
The failure mode we are seeing is pin 31 - HIDRV1 - is shorted to GND, pin 28 - REGN - is ~1 V and Battery Management Studio is not able to read any of the ADC registers (0x26, 0x28, 0x2A, 0x2C). VBUS is 15 V.
Any ideas of what may be causing this? We are still troubleshooting on our side.
Thanks,
Kevin
