Description
The TLE7259-2GE 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 TLE7259-2GE 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 TLE7259-2GE can
be used in all automotive applications.
Different operation modes and the INH output allow the TLE7259-2GE to control external components, like voltage
regulators. In Sleep-mode the TLE7259-2GE draws less than 8 µA of quiescent current 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
TLE7259-2GE 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 TLE7259-2GE provides excellent ESD Robustness
together with a very high electromagnetic immunity (EMI). The TLE7259-2GE 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 existing on the same monolithic circuit. The TLE7259-2GE and the Infineon SPT^® technology are
AEC qualified and tailored to withstand the harsh condition of the Automotive Environment.
