BQ79616PAPRQ1 General Description

Featuring integrated front-end filters, the BQ79616PAPRQ1 allows for the implementation of simple, low voltage-rated differential RC filters on the cell input channels. This results in filtered, DC-like voltage measurements that are crucial for precise state of charge (SOC) calculations. Moreover, the device incorporates autonomous internal cell balancing capabilities, complete with temperature monitoring functionality to prevent overheating during the balancing process

Key Features

Achieve precise temperature and voltage monitoring
Monitor individual battery cells up to 16 series-connected
