Quad LIN Transceiver

The TLIN1024-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 17987–4.2 standards.

LIN is a single wire bidirectional bus typically

used for low speed in-vehicle networks using data

rates up to 20 kbps. The LIN receiver supports

data rates up to 100 kbps for in-line programming.

The TLIN1024-Q1 has two separate dual LIN

transceiver blocks. The VSUP1/2 control

separate dual transceiver blocks. The TLIN1024-Q1

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. The integrated resistor,

electrostatic discharge (ESD) protection, and

fault protection allow designers to save board

space in their applications.
