XB4908 SERIES
One Cell Lithium-ion/Polymer Battery Protection IC
GENERAL DESCRIPTION
The XB4908 SERIES product is a high integration solution for lithium-ion/polymer battery protection. XB4908 SERIES contai -ns advanced p-ower MOSFET, high-accur acy voltage det-ection circuits and delay ci -rcuits. XB4908 SERIES is put into an ultra -small ESN4 package and only one external component makes it an ideal solution in limited space of battery pack. XB4908 SERIES has all the protection fu -nctions required in the battery application i -ncluding overcharging, overdischarging, o vercurrent and load short circuiting protecti -on etc. The accurate overcharging detection voltage ensures safe and full utilization charging. The low standby current drains lit tle current from the cell while in storage. The device is not only targeted for digital cellular phones, but also for any other Li-Io n and Li-Poly battery-powered information appliances requiring long-term battery life.
