LTC2944IDD#TRPBF

Battery Management Overview

The LTC2944IDD#TRPBF is a battery gas gauge designed for multi-cell lithium-ion applications with an operating voltage range of 3.6 V to 60 V. It features a precision analog coulomb counter that integrates current measured through an internal sense resistor. The device utilizes an internal 14-bit no-latency ADC to measure voltage, current, and temperature simultaneously. These measurements are stored in internal registers accessible via an SMBus/I2C interface.
