GENERAL DESCRIPTION

The XB8608A Series product is a high

integration solution for lithiumion/polymer battery protection.

XB8608A contains advanced power

MOSFET, high-accuracy voltage

detection circuits and delay circuits.

XB8608A is put into an SOP8 package

and only one external component

makes it an ideal solution in limited

space of battery pack.

XB8608A 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 longterm battery life.
