3 Description

The TLIN1028-Q1 is a local interconnect network

(LIN) physical layer transceiver, compliant to LIN 2.2A

ISO/DIS 17987–4.2 standards, with an integrated low

dropout (LDO) voltage regulator.

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

end-of-line

programming.

The

TLIN1028-Q1 converts the LIN protocol data stream

on the TXD input into a LIN bus signal. The receiver

converts the data stream to logic level signals that

are sent to the microprocessor through the open-

drain RXD pin. The TLIN1028-Q1 reduces system

complexity by providing a 3.3 V or 5 V rail with up to

70 mA (D) and 125 mA (DRB and DDA) of current to

power microprocessors, sensors or other devices.

The TLIN1028-Q1 has an optimized current-limited

wave-shaping driver which reduces electromagnetic

emissions (EME).
