CXPR7149 product is a high integration solution for lithium-ion/polymer battery protection. contains advanced power MOSFET high-accuracy voltage detection circuits and delay circuits

The CXPR7149 product is a high integration solution for lithium-ion/polymer
battery protection. CXPR7149 contains advanced power MOSFET, high-accuracy
voltage detection circuits and delay circuits.
CXPR7149 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.
CXPR7149 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 long-term
battery life.

七,功能概述f61嘉泰姆


The CXPR7149 monitors the voltage and current of a battery and protects it from being damaged due to overcharge voltage,overdischarge voltage, overdischarge current, and short circuit conditions by disconnecting the battery from the load or charger. These functions are required in order to operate the battery cell within specified limits.f61嘉泰姆
