The Infineon LIN transceiver with integrated voltage regulator 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 under voltage 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 voltage regulator is especially suited for applications that are permanently supplied by the battery.

Very low leakage current on the BUS pin
VCC under voltage detection with RESET output
TxD protected with dominant time-out function
BUS short to VBAT protection and BUS short to GND handling
Over temperature protection and supply under voltage detection
