ADBMS2950WCCSZ

Overview

The ADBMS2950WCCSZ is a battery pack monitor designed for electric and hybrid vehicles. It measures current flow via low-offset shunt sensing and detects overcurrent conditions using a fast ADC with digital threshold comparers, signaling results through a dedicated alert line. The device features twelve high-impedance buffered inputs for monitoring cell voltages, temperatures, and system status. It includes six programmable general-purpose outputs to control external disconnect transistors and four general-purpose inputs for flexible configuration.
