Features
1. 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 han-
dling. Sleep Mode guarantees minimal current consumption. The ATA6662 has
advanced EMI and ESD performance.
