Description
The LTC2944IDD#PBF is a high-precision battery gas gauge IC designed to monitor all critical parameters of a battery pack. Operating with an input voltage range of up to 60V, it is specifically engineered for multicell applications. This device measures battery charge, voltage, current, and temperature with high accuracy, providing essential data for sophisticated battery management systems.
By monitoring the charge entering or leaving the battery (coulomb counting), the LTC2944 allows for an extremely accurate estimation of the battery’s state of charge. Its integrated I2C interface makes it easy to communicate with a system microcontroller, allowing for real-time monitoring and advanced battery state estimation in demanding portable or stationary energy storage applications.
