    Hello Ryuji

    OVP:

    1. The USB recommended max input voltage is 6V with absolute max of 7V.

    2. Max AC input is 16V with absolute max of 18V

      1. The bq24035 has AC input cutoff protection, at 6.4V the AC input FET will disconnect input.

     

    Overcharge Protection:

    1. Max Output voltage is regulated to 4.2V with +/- 1% accurate over temp

    2. Charge current for all phase of charge is controlled by the device, set by ILIM1/2 pin

    3. Timer will limit charge duration, set by resistor on TMR pin

    4. TS pin available for Batter NTC to limit thermal rise.
