Description

The ATA6662 is a fully integrated LIN transceiver complying with the LIN specification 2.0, 2.1 and SAEJ2602-2. It interfaces the LIN protocol handler and the physical layer. The device is designed to handle the low-speed data communication in vehicles, for example, 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. Sleep Mode guarantees minimal current consumption. The ATA6662 has advanced EMI and ESD performance.
