七,功能概述SVh嘉泰姆

The CXPR7144I monitors the voltage and current of a battery and protects it fromSVh嘉泰姆
being damaged due to overcharge voltage,overdischarge voltage, overdischargeSVh嘉泰姆
current, and short circuit conditions bydisconnecting the battery from the loadSVh嘉泰姆
or charger. These functions are required inorder to operate the battery cell withinSVh嘉泰姆
specified limits.SVh嘉泰姆
The device requires only one external capacitor. The MOSFET is integrated andSVh嘉泰姆
its RDS(ON) is as low as 45mΩ typical.SVh嘉泰姆
