XB5350A
XB5350A is One Cell Lithium-ion/Polymer Battery Protection manufactured by XySemi.
DESCRIPTION
The XB5350A product is a high integration solution for lithiumion/polymer battery protection. XB5350A contains advanced power MOSFET, high-accuracy voltage detection circuits and delay circuits. XB5350A is put into an ultra-small SOT23-5 package and only one external ponent makes it an ideal solution in limited space of battery pack. XB5350A 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.
