XB4908 SERIES One Cell Lithium-ion/Polymer Battery Protection IC GENERAL DESCRIPTION The XB4908 SERIES product is a high i ntegration solution for lithium-ion/polymer battery protection. XB4908 SERIES contai ns advanced power MOSFET, high-accura cy voltage detection circuits and delay circ uits. XB4908 SERIES is put into an ultra-s mall ESN4 package and only one external component makes it an ideal solution in li mited space of battery pack. XB4908 SERIES has all the protection fu nctions required in the battery application i ncluding overcharging, over-discharging, o vercurrent and load short circuiting protecti on etc. The accurate overcharging detectio n voltage ensures safe and full utilization c harging. The low standby current drains littl e current from the cell while in storage.
