Hi. I am experiencing a strange problem with BQ24091, when charging a standard single-cell Li-ion battery.
After the first charge cycle (battery is correctly charged up to 4.20v), the power good led turns slightly on even without connecting V_CHG. The measured voltage on TP_3 (between V_BAT and the PG pin) is 1.65v.
The leds behaviour while charging the battery is correct.
Should I put a pull-up on PG pin?
