The Microchip ATA663211 is a fully integrated LIN transceiver designed in compliance with the LIN specification 2.0, 2.1, 2.2, 2.2A 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 busensures data communication up to 20Kbaud. Sleep mode guarantees minimal current consumption even in the case of a floating bus line or a short circuit on the LIN bus to GND. The device is available in SO8 package and DFN8 package with wettable flanks for automatic optical inspection.
