供应XB9121A 赛芯微1节锂电芯片 DFN-12封装

　　GENERAL DESCRIPTION

　　The XB9121Aproduct is a high integration solution for lithiumion/ polymer battery protection.

　　XB9121Acontains advanced power MOSFET, high-accuracy voltage detection circuits and delay circuits.

　　XB9121Ais put into an ultra-small DFN-12 package and only one external component makes it an ideal solution in limited space of battery pack.

　　XB9121Ahas 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.
