BATTERY MANAGEMENT

ONE CELL LITHIUM-ION/POLYMER BATTERY PROTECTION IC

DESCRIPTION

FEATURES

The A4002 series product is a high integration

solution for lithium-ion/polymer battery protection.

A4002 contains advanced power MOSFET,

high-accuracy voltage detection circuits and delay

circuits. A4002 is put into a small package and only

one external component makes it an ideal solution

in limited space of battery pack. A4002 has all the

protection functions required in the battery



Protection of Battery Cell Reverse Connection

Integrate MOSFET

Over-temperature Protection

Two-step Overcurrent Detection:

Over-discharge Current

Load Short Circuiting



Charger Detection Function

0V Battery Charging Function

High-accuracy Voltage Detection

Low Current Consumption

Operation Mode: 4uA typ

application

including

overcharging,

over-discharging, overcurrent and load short

circuiting protection etc. The accurate safe and full

utilization charging. The low standby current drains

little current from the cell while in storage. The

device is only targeted for digital cellular phones,

but also for any other Li-ion and Li-Poly

battery-powered information appliance requiring

long-term battery life.



Power-down Mode: 2.0uA typ

Available in SOT-23S and SOT-25 Packages

APPLICATION

The A4002 is available in SOT-23S and SOT-25

packages.
