The BQ79600-Q1 is a communication (bridge) IC designed to interface between microcontroller (MCU) and TI battery monitoring ICs, for example the BQ7961X-Q1 and BQ79606A-Q1. The information from the MCU is translated by the device to signals recognized by TI’s battery management daisy chain protocol, and transmitted out. And signals from daisy chain are decoded to bit stream and then sent back to MCU.
