Description
The TLE7259G 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
TLE7259G 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 TLE7259G can be used in all
automotive applications.
Different operation modes and the INH output allow the TLE7259G to control external components, like voltage
regulators. In Sleep-mode the TLE7259G draws less than 8 µA of quiescent while still being able to wake up off
of LIN bus traffic and a local wake-up input. The very low leakage current on the BUS pin makes the TLE7259G
especially suitable for “Mixed Power Supply“ applications and supports the low quiescent current requirements of
the LIN network.
Based on the Infineon Smart Power Technology SPT^®, the TLE7259G provides excellent ESD Robustness
together with a very high electromagnetic immunity (EMI). The TLE7259G reaches a very low level of
electromagnetic emission (EME) within a broad frequency range and independent form the battery voltage.
The Infineon Smart Power Technology SPT^® allows bipolar and CMOS control circuitry in accordance with DMOS
power devices existing on the same monolithic circuit. The TLE7259G and the Infineon SPT^® technology are AEC
qualified and tailored to withstand the harsh condition of the Automotive Environment.
