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
