TLIN1022-Q1中文资料Dual Local Interconnect Network (LIN) Transceiver With Dominant State Timeout数据手册TI规格书

描述 Description

The TLIN1022-Q1device is a Dual Local Interconnect Network (LIN) physical layer transceiver with integratedwake-up and protection features, complaint to LIN 2.0, LIN 2.1, LIN 2.2, LIN 2.2A and ISO/DIS17987–4.2 standards. LIN is a single wire bidirectional bus typically used for low speed in-vehiclenetworks using data rates up to 20 kbps. The TLIN1022-Q1 is designed to support 12 V applications with wider operating voltage and additional bus-faultprotection. The LIN receiver supports data rates up to 100 kbps for in-line programming. TheTLIN1022-Q1 converts the LINprotocol data stream on the TXD input into a LIN bus signal using a current-limited wave-shapingdriver which reduces electromagnetic emissions (EME). The receiver converts the data stream tologic level signals that are sent to the microprocessor through the open-drain RXD pin. Ultra-lowcurrent consumption is possible using the sleep mode which allows wake-up via LIN bus or pin.
