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.
