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.
