Description
AI
The BQ79600-Q1 is a communication (bridge) IC designed to interface between a microcontroller (MCU) and TI battery monitoring ICs, for example the BQ7961X-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.
When the MCU and PMIC are in SHUTDOWN/ SLEEP, the BQ79600-Q1 can wake them up if any unmasked fault is detected when using ring architecture.
