The TLE8458G and its derivatives TLE8458GV33, TLE8458GU and TLE8458GUV33, 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 TLE8458Gx is pin compatible to stand-alone LIN transceivers like the TLE7259-2GE. 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 TLE8458G 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 TLE8458G can be used in all automotive applications. Based on the Infineon Smart Power Technology SPT®, the TLE8458Gx provides excellent ESD robustness together with a very high electro-magnetic immunity (EMI). The TLE8458Gx reaches a very low level of electromagnetic emission (EME) within a broad frequency range. The TLE8458Gx family and the Infineon SPT® technology are AEC qualified and tailored to withstand the harsh conditions in the automotive environment
