Hi,
I am using BQ25790EVM to charge a 4S1P battery pack from a 12V input supply. Please find attached the setup picture. The evaluation board isn't charging the battery but the following conditions are valid:
1. The EN_CHG bit is set to 1 and CE pin is LOW.
2. No thermistor fault on TS pin.
3. No safety timer fault.
The battery voltage is @ 15.62V and I have attached register data for your reference. If you can point me in the right direction, that would be great.
