Description

The TLE8457C / TLE8457D is a monolithic integrated LIN transceiver and low drop-out voltage regulator. The device is designed to supply a microcontroller and peripherals with up to 70 mA, provide protection through VCC undervoltage reset, while also offering bi-directional bus communication compliant to LIN specification 2.2 A and SAE J2602. With the ultra low quiescent current consumption of typical 20 µA in standby mode the TLE8457C / TLE8457D is especially suited for applications that are permanently supplied by the battery.

Based on the Infineon BiCMOS technology the TLE8457C / TLE8457D provide excellent ESD robustness together with a very high level of electromagnetic compatibility (EMC). The TLE8457C / TLE8457D is AEC qualified and tailored to withstand the harsh conditions of the automotive environment.
