A4102
LDO MODE OVP WITH INTEGRATED P-MOSFET BATTERY MANAGEMENT
DESCRIPTION
The A4102 is Li+ charger IC with integrated P-MOSFET.
The device is fabricated with advanced CMOS technology to achieve maintaining low static power dissipation over a very broad VCC operating range.
The A4102 integrates a P-MOSFET and
Schottky diode which is normally a discrete device employed for conventional battery charging design of mobile phone system.
In addition to that, A4102 works like a LDO mode to keep CHRIN voltage stable when ACIN goes high.
And thus it will not trigger the CHRIN pin over-voltage protection when ACIN voltage increased to as high as 15V.
