TLE8457B Overview
The TLE8457A / TLE8457B 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 munication pliant to LIN specification 2.2 A and SAE J2602. With the ultra low quiescent current consumption of typical 20 µA in standby mode...
