A4102

AiT Semiconductor Inc. www.ait-ic.com 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. FEATURES  A Built-In P-MOSFET  LDO mode makes CHRIN voltage stable around 5.5V  Range of operation input voltage: Max 15V  Charging current up to 1A  Environment Temperature: -20℃ ~ 85℃  Available in DFN8(2x2) Package APPLICATION  Cell phone and other portable device The A4102 provides complete Li+ charger protections and saves the external MOSFET and Schottky diode for the charger of cell phone’s PMIC. It is available in a DFN8(2x2) package. TYPICAL APPLICATION The above features and small package make the A4102 an ideal part for cell phones applications. The A4102 is available in DFN8(2x2) Package.
