3 Description

The TLIN1029-Q1 is a Local Interconnect Network

(LIN) physical layer transceiver with integrated wake-

up and protection features, complaint to LIN 2.0, LIN

2.1, LIN 2.2, LIN 2.2A, ISO/DIS 17987–4.2 and IBEE

Zwickau standards. LIN is a single wire bidirectional

bus typically used for low speed in-vehicle networks

using data rates up to 20 kbps. The TLIN1029-Q1 is

designed to support 12 V applications with wider

operating voltage and additional bus-fault protection.

The LIN receiver supports data rates up to 100 kbps

for in-line programming. The TLIN1029-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 pin. The integrated

resistor, ESD and fault protection allows designers to

save board space in their applications.
