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.
