3.2 Description

The LIN-SBC is a fully integrated LIN transceiver, which complies with the LIN 2.0, 2.1 and

SAEJ2602-2 specifications. It has a low-drop voltage regulator with a 5V/50mA output and a

window watchdog.

The LIN-SBC is designed to handle the low-speed data communication in vehicles, e.g., in

convenience electronics. Improved slope control at the LIN-driver ensures secure data com-

munication up to 20kBaud. Sleep Mode and Silent Mode guarantee very low current

consumption.
