XB5556A2

XB5556A2 ______________________________________ ________________________________________________________ _________________________ One Cell Lithium-ion/Polymer Battery Protection IC GENERAL DESCRIPTION The XB5556A2 product is a high integration solution for lithiumion/polymer battery protection. XB5556A2 contains advanced power MOSFET, high-accuracy voltage detection circuits and delay circuits. XB5556A2 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. XB5556A2 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-power...
