XB8989AF单节锂电池保护IC放电过流18A,充电过流14A,最大持续放电电流9A

XB8989AF单节锂电池保护IC放电过流18A,充电过流14A,最大持续放电电流9A

过充4.3-4.475V可选,针对不同电池电芯,过放2.4-2.8V可选,放电过流18A,充电过流14A,最大持续放电电流9A,采用ESOP8封装,单颗适用于22.5W的移动电源,常用于搭配IP5328以及智融系列快充芯片使用。

 

GENERAL DESCRIPTION

The XB8989AF Series product is a high

integration solution for lithium

ion/polymer battery protection.

XB8989AF contains advanced power

MOSFET, high-accuracy voltage

detection circuits and delay circuits.

XB8989AF is put into an SOP8-PP

package and only one external

component makes it an ideal solution in

limited space of battery pack.

XB8989AF 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.
