Xysemi/赛芯微 XB4302A TSOT23-4 单电池锂离子/聚合物电池保护IC

GENERAL DESCRIPTION

The XB4302A series product is a high integration solution for lithiumion/polymer battery protection. XB4302A contains advanced power MOSFET, high-accuracy voltage detection circuits and delay circuits. XB4302A is put into an ultra-small TSOT23-4 package and only one external component makes it an ideal solution in limited space of battery pack.

XB4302A 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.

APPLICATIONS

● One-Cell Lithium-ion Battery Pack

● Lithium-Polymer Battery Pack
