Texas Instruments

 

Description

TLIN2029A-Q1은 웨이크업 및 보호 기능이 통합되어 있고 LIN 2.0, LIN 2.1, LIN 2.2, LIN 2.2 A 및 ISO/DIS 179874 표준을 준수하는 로컬 상호 연결 네트워크(LIN) 물리 계층 트랜시버입니다. LIN은 최대 20kbps의 데이터 속도를 사용하는 차량 내 네트워크에 일반적으로 사용되는 단선 양방향 버스입니다. TLIN2029A-Q1은 더 넓은 작동 전압과 추가적인 버스 오류 보호 기능을 갖춘 12V 및 24V 애플리케이션을 지원하도록 설계되었습니다.
 LIN 수신기는 더 빠른 인라인 프로그래밍을 위해 최대 100kbps의 데이터 속도를 지원합니다. TLIN2029A-Q1은 EME(전자기 방출)를 줄이는 전류 제한 파형 형성 드라이버를 사용하여 TXD 입력의 데이터 스트림을 LIN 버스 신호로 변환합니다. 수신기는 데이터 스트림을 오픈 드레인 RXD 핀을 통해 마이크로프로세서로 전송되는 논리 레벨 신호로 변환합니다. LIN 버스 또는 EN 핀을 통해 절전 모드를 해제할 수 있는 절전 모드를 사용하면 초저전류 소비가 가능합니다.
 TLIN2029A-Q1은 LIN 응답기 노드 애플리케이션용 저항기, ESD 보호 및 오류 보호 기능을 통합하여 애플리케이션에서 외부 구성 요소의 양을 줄일 수 있습니다. 이 장치는 접지 이동 또는 공급 전압 연결이 끊어진 경우 LIN을 통해 공급 입력으로 역류되는 전류를 방지합니다. TLIN2029A-Q1에는 저전압 감지, 온도 차단 보호, 접지 손실 보호 기능도 포함되어 있습니다.

너희는 오직 만군의 여호와, 주님만을 거룩하다고 하여라. 

주님만이 너희가 두려워하며 떨어야 할 분이시다.
