Overview

The LTC2944 is a high-side multicell battery gas gauge designed to measure charge, voltage, current, and temperature in systems up to 60V. It integrates a programmable internal 14-bit ADC and uses a precision sense resistor to track battery state-of-charge with high accuracy via an I2C/SMBus interface.

Why Choose This Part

The 60V operating range eliminates the need for external level-shifting circuitry in high-voltage stacks, reducing BOM complexity. Its high-side sensing architecture and integrated 14-bit ADC ensure precise energy tracking across wide dynamic ranges of load current.

Applications

Multi-Cell Battery Packs
Ideal for tracking state-of-charge in high-voltage lithium-ion or lead-acid battery strings used in backup power systems.
Electric Vehicle Subsystems
Monitors energy consumption and battery health in light electric vehicles, drones, and robotics.
Industrial Power Tools
Provides precise fuel gauging for high-voltage cordless equipment requiring robust voltage and current monitoring.
Telecom Backup Systems
Enables remote monitoring of battery capacity and discharge rates in 48V telecom infrastructure applications.

Getting Started

Engineers should use the DC1812A demonstration circuit to evaluate the LTC2944's performance. The device communicates via I2C, so a microcontroller with an I2C master and the QuikEval system software can be used for rapid prototyping and configuration of alarm thresholds.
