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.

BQ79600EVM — 具備自動主機喚醒功能且符合功能安全規範的 SPI/UART 轉菊鍊橋接器介面評估模組

BQ79600EVM 是 BQ79600-Q1 裝置的評估模組 (EVM)，用作橋接器 IC，以在微控制器 (MCU) 和 TI 電池監控 IC（例如 BQ7961X-Q1 和 BQ79606A-Q1）之間介接。MCU 的資訊會由此裝置轉換為 TI 電池管理菊鍊通訊協定辨識並傳送出去的脈衝。此裝置具備自動主機喚醒功能，可搭配 BQ7961X-Q1 系列使用，當電池監控 IC 中偵測到未遮蔽故障時，可透過 INH 針腳自動喚醒主機。
