产品概述 返回TOP
The CXPR7140 is a high integrated solution for lithium/polymer battery protection. CXPR7140 contains advanced power MOSFET, high-accuracy voltage detection circuits and delay circuits. CXPR7140 is put into an ultra-small SOT23-5 package and only one external component makes it an ideal solution in limited space of battery pack.CXPR7140has all the protection functions required in the battery application including over charging, over discharging, over current and load short protection etc. The accurate over charging 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 long time battery life.
