GENERAL DESCRIPTION

The XB8089A Series product is a high

integration solution for lithiumion/polymer battery protection.

XB8089A contains advanced power

MOSFET, high-accuracy voltage

detection circuits and delay circuits.

XB8089A is put into an SOP8-PP

package and only one external

component makes it an ideal solution in

limited space of battery pack.

XB8089A 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.
