GENERAL DESCRIPTION
The product is a high integration solution for lithiumion/polymer battery protection.contains advanced powerMOSFET, high-accuracy voltage detection circuits and delay circuits.is put into an ultra-small SOT23-5 package and only one external component makes it an ideal solution in limited space of battery pack.has all the protection functions required in the battery application includingovercharging, 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
