ATA6661
Description
The ATA6 66 1 is a fu lly int egrat ed LIN tran sce iver acc or din g to th e L IN
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.
