Description
The TLE7259-2GU is a follow-up product of the TLE7259-2GE. It provides the same functions and it is pin
compatible to the TLE7259-2GE. The TLE7259-2GU is designed for in-vehicle networks using data transmission
rates from 2.4 kBaud to 10.4 kBaud according to the SAE J2602 standard. The TLE7259-2GU 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 TLE7259-2GU can be used in all automotive applications.
Different operation modes and the INH output allow the TLE7259-2GU to control external components, like voltage
regulators. In Sleep-mode the TLE7259-2GU 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
TLE7259-2GU 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 TLE7259-2GU provides excellent ESD Robustness
together with a very high electromagnetic immunity (EMI). The TLE7259-2GU 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 TLE7259-2GU and the Infineon SPT^® technology are
AEC qualified and tailored to withstand the harsh condition of the Automotive Environment.
