One Cell Lithium-ion/Polymer Battery Protection IC
- DESCRIPTION
The HM5464A series product is a high integration solution for lithium-ion/polymer battery protection. HM5464A contains advanced power MOSFET, high-accuracy voltage detection circuits and delay circuits. HM5464A is put into a small package and only one external ponent makes it an ideal solution in limited space of battery pack. HM5464A has all the protection functions required in the battery application including overcharging, over-discharging, overcurrent and load short circuiting protection etc. The accurate safe and full utilization charging. The low standby current drains little current from the cell while in storage. The device is only targeted for digital cellular phones, but also for any other Li-ion and Li-Poly battery-powered information appliance requiring long-term battery life.
