integration solution for lithium-ion/polymer battery protection. XB4908 J SERIES cont ains advanced power MOSFET, high-accu racy voltage detection circuits and delay ci -rcuits. XB4908 J SERIES is put into an ult ra-small ESN4 package and only one exter nal component makes it an ideal solution i n limited space of battery pack. XB4908 J SERIES has all the protection functions required in the battery application including 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.
