3.2 Description

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

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

dow watchdog.

The LIN-SBC are 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 commu-

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