Description

The TLE8458G and TLE8458GV33 integrate a low drop voltage regulator and a LIN transceiver on one monolithic

circuit. The device is suitable to supply microcontrollers and driving a LIN bus at the same time. The TLE8458 is

pin compatible to stand-alone LIN transceivers like the TLE7259-3GE. The combination of a voltage regulator and

a LIN transceiver on one circuit decreases the quiescent current for a typical application to a value of 8 μA, while

the TLE8458 is still able to wake-up off a LIN bus signal or a signal change on the local wake-up input WK.

Compliant to all LIN standards and with a wide operational supply range, the TLE8458 can be used in all

automotive applications.

Based on the Infineon Smart Power Technology SPT®, the TLE8458 provides excellent ESD robustness together

with a very high electro-magnetic immunity (EMI). The TLE8458 reaches a very low level of electro-magnetic

emission (EME) within a broad frequency range. The TLE8458 family and the Infineon SPT® technology are AEC

qualified and tailored to withstand the harsh conditions in the automotive environment.
