TLIN2024A-Q1 - Quad Local Interconnect Network (LIN) Transceiver with Dominant State Timeout

TLIN2024A-Q1  - Quad Local Interconnect Network (LIN) Transceiver with Dominant State Timeout

 

Texas Instruments

 

Description

 The TLIN2024A-Q1 device is a Quad Local Interconnect Network (LIN) physical layer transceiver, which integrates wake-up and protection features, compliant to LIN2.0, LIN2.1, LIN2.2, LIN2.2A and ISO/DIS 17987–4 standards. LIN is a single wire bidirectional bus typically used for low speed in vehicle networks using data rates up to 20 kbps. The TLIN2024A-Q1 is designed to support 12-V and 24-V applications with wider operating voltage and additional bus-fault protection. The device has two separate dual LIN transceiver blocks. The VSUP1/2 control separate dual transceiver blocks.
 The TLIN2024A-Q1 receiver supports data rates up to 100 kbps for faster in-line programming. The device converts the LIN protocol data stream on the TXD input into a LIN bus signal using a current-limited wave-shaping driver which reduces electromagnetic emissions (EME). The receiver converts the data stream to logic level signals that are sent to the microprocessor through the open-drain RXD pin. Ultra-low current consumption is possible using the sleep mode which allows wake-up via LIN bus or EN pin.

 

TLIN2024A-Q1 장치는 웨이크업 및 보호 기능을 통합한 Quad Local Interconnect Network(LIN) 물리 계층 트랜시버로, LIN2.0, LIN2.1, LIN2.2, LIN2.2A 및 ISO/DIS 17987–4 표준을 준수합니다. LIN은 일반적으로 최대 20kbps의 데이터 속도를 사용하는 차량 네트워크에서 저속에 사용되는 단일 와이어 양방향 버스입니다. TLIN2024A-Q1은 더 넓은 작동 전압과 추가 버스 오류 보호 기능을 갖춘 12V 및 24V 애플리케이션을 지원하도록 설계되었습니다. 이 장치에는 두 개의 별도 듀얼 LIN 트랜시버 블록이 있습니다. VSUP1/2는 별도 듀얼 트랜시버 블록을 제어합니다.
TLIN2024A-Q1 수신기는 더 빠른 인라인 프로그래밍을 위해 최대 100kbps의 데이터 속도를 지원합니다. 이 장치는 TXD 입력의 LIN 프로토콜 데이터 스트림을 전자기 방출(EME)을 줄이는 전류 제한 파형 형성 드라이버를 사용하여 LIN 버스 신호로 변환합니다. 수신기는 데이터 스트림을 오픈 드레인 RXD 핀을 통해 마이크로프로세서로 전송되는 논리 레벨 신호로 변환합니다. LIN 버스 또는 EN 핀을 통해 웨이크업을 허용하는 슬립 모드를 사용하면 매우 낮은 전류 소비가 가능합니다.
