BQ79600-Q1 Automotive SPI/UART Communication Interface

반응형

 

BQ79600-Q1 - Automotive SPI/UART Communication Interface Functional-Safety Compliant With Automatic Host Wakeup

 

TEXAS INSTRUMENTS

 

Description

BQ79600-Q1은 마이크로컨트롤러(MCU)와 TI 배터리 모니터링 IC(예: BQ7961X-Q1) 사이를 인터페이스하도록 설계된 통신(브리지) IC입니다. MCU의 정보는 장치에 의해 TI의 배터리 관리 데이지 체인 프로토콜에서 인식되는 신호로 변환되어 전송됩니다. 그리고 데이지 체인의 신호는 비트 스트림으로 디코딩된 다음 다시 MCU로 전송됩니다.
MCU 및 PMIC가 SHUTDOWN/SLEEP 상태일 때 BQ79600-Q1은 링 아키텍처를 사용할 때 마스크되지 않은 오류가 감지되면 이를 깨울 수 있습니다.
