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.
Based on the Infineon Smart Power Technology SPT
®
, the TLE7269G provides excellent ESD robustness
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.
The Infineon Smart Power Technology SPT
®
allows bipolar and CMOS control circuitry in accordance with DMOS
power devices to exist on the same monolithic circuit. The TLE7269G and the Infineon SPT
®
technology are AEC
qualified and tailored to withstand the harsh conditions of the Automotive Environment.
