Description

The TLE7269G is a transceiver for the Local Interconnect Network (LIN) with integrated Wake-Up and protection

features. It is designed for in-vehicle networks using data transmission rates from 2.4 kBaud to 20 kBaud. The

TLE7269G functions as a bus driver between the protocol controller and the physical bus inside the LIN network.

Compliant to all LIN standards and with a wide operational supply range the TLE7269G can be used in all

automotive applications.

Two stand-alone LIN transceivers are integrated on one monolithic circuit inside TLE7269G. Both transceivers

offer different operation modes and separate INH outputs to control external circuitry, like voltage regulators. In

Sleep-mode the TLE7269G draws less than 10

µA of quiescent current for both integrated LIN Transceivers, while

both transceivers are still able to wake up off of LIN bus traffic or the local Wake-Up input. The very low leakage

current on the BUS pins makes the TLE7269G especially suitable for partially supplied networks and supports the

low quiescent current requirements of the LIN network.

together with a very high electromagnetic immunity (EMI). The TLE7269G reaches a very low level of

electromagnetic emission (EME) within a broad frequency range and independent from the battery voltage.
