We are using LTC4162IUFD-LAD#PBF in one of our design and facing below issue
- All most 10 % board don't pick charging if battery voltage below 10V, While same battery work fine on OK board.
- Following is schematic of LTC4162. Here Capacitor C50 and C51 changed to 10uF/50V due to continues failure of 47uF/25V
- Battery is 3*3.7V Lithium Ion Cell 4800mAH with protection circuit.
- Input Voltage : 15.92V
Input Current : 0.13A
Battery Voltage : 10.04V
Battery Current : -1.00mA
Charger_state : battery_detection
Charger_status : charger_off
Battery Charge : 0%
