GENERAL DESCRIPTION The HM5496A Series product is a high integration solution for lithiumion/polymer battery protection. HM5496A contains advanced power MOSFET， high-accuracy voltage detection circuits and delay circuits. HM5496Ais put into an SOT89-3 package and only one external component makes it an ideal solution in limited space of battery pack. HM5496A 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.
