七,功能概述
The CXPR7144I 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 bydisconnecting the battery from the load
or charger. These functions are required inorder to operate the battery cell within
specified limits.
The device requires only one external capacitor. The MOSFET is integrated and
its RDS(ON) is as low as 45mΩ typical.
