            BQ79600-Q1 Automotive SPI/UART Communication Interface
                    Texas Instruments' interface features automatic host wakeup and is functional safety compliant
    

Image of Texas Instruments' BQ79600-Q1 Automotive SPI/UART Communication Interface Texas Instruments' BQ79600-Q1 is a communication (bridge) IC designed to interface between a microcontroller (MCU) and TI battery-monitoring ICs. The information from the MCU is translated by the device to signals recognized by TI’s battery management daisy chain protocol, and transmitted out. Signals from the daisy chain are decoded to bit stream and then sent back to the 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.
