3 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 invehicle

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.
