Description

The ATA6661 is a fully integrated LIN transceiver according to the LIN

specification 2.0. It interfaces the LIN protocol handler and the physical layer. The

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

convenience electronics. Improved slope control at the LIN bus ensures secure data

communication up to 20 kBaud with an RC-oscillator for protocol handling. In order to

comply with the 42-V power net requirements, the bus output is capable of withstand-

ing high voltages. Sleep mode guarantees minimal current consumption.
