XB7608A

______________________________________ ________________________________________________________________

One Cell Lithium-ion/Polymer Battery Protection IC

GENERAL DESCRIPTION

The XB7608A series product is a high

integration solution for lithium-

ion/polymer battery protection.

XB7608A contains advanced power

MOSFET, high-accuracy voltage

detection circuits and delay circuits.

XB7608A is put into an ultra-small

CPC5 package and only one external

component makes it an ideal solution in

limited space of battery pack.

XB7608A has all the protection functions

required in the battery application including

overcharging, overdischarging, overcurrent

and load short circuiting protection etc. The

accurate overcharging detection voltage

ensures safe and full utilization charging.

The low standby current drains little current

from the cell while in storage.

The device is not only targeted for digital

cellular phones, but also for any other

Li-Ion and Li-Poly battery-powered

information appliances requiring long-

term battery life.

FEATURES

· Protection of Charger Reverse

Connection

· Protection of Battery Cell Reverse

Connection

· Integrate Advanced Power MOSFET

with Equivalent of 14.5mΩ R

SS(ON)

· Ultra-small CPC5 Package

· Only One External Capacitor

Required

· Over-temperature Protection

· Overcharge Current Protection

· Two-step Overcurrent Detection:

-Overdischarge Current

-Load Short Circuiting

· Charger Detection Function

· 0V Battery Charging Function

- Delay Times are generated inside

· High-accuracy Voltage Detection

· Low Current Consumption

- Operation Mode: 3.9μA typ.

- Power-down Mode: 2.2

μA typ.

· RoHS Compliant and Lead (Pb) Free
