Tool/software:
Please review the BQ29707DSER protection IC Schematic. I am using it for 3.7V nominal 4.2V max 50mAH Lithium-ion battery. II am using Wireless power receiver IC LTC4124 to charge the battery. BAT pin of LTC4124 is going directly to battery. And charge voltage is set at 4.2V and Charge current is set at 25mA. My main purpose of using the protetion IC is to keep my battery save from deep discharge and over charge.
