产品概述 返回TOP
The CXPR7181 product is a high integration solution for lithiumion/polymer
battery protection.CXPR7181 contains advanced powerMOSFET, high-accuracy
voltage detection circuits and delay circuits.CXPR7181 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.CXPR7181 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.
