Hello all,
I have designed a schematic and tried to use BQ25101H for battery Li-Ion 3.7 200 mAh.
In datasheet there is no example for /CHG schematic. it is only for Pre-term pin. i know it is easy to design schematic for /CHG pin package but it has got lots of notes.
The problem is that the led charge wouldn't turn off after full charge. i have used other charger and when they exactly reach at 4.2 v, the current would drop and led charge would turn off.
i only need this structure; if no battery, Led would turn off, and only in charge, led would turn on until being fully charged. in the BQ25101H the voltage wouldn't turn off with my 4.2 V battery.
does anyone can modify my schematic if it has got any problem?
I will appreciate for you help.
