产品概述 返回TOP
high-accuracy voltage detection circuits and delay circuits. CXPR7182 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.CXPR7182 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.
