七,功能概述
The CXPR7145D 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.
The device requires only one external capacitor. The MOSFET is integrated and its RDS(ON) is as low as 45mΩ typical.
