Atmel ATA6663全集成LIN收发方案

Atmel 公司的ATA6663是全集成LIN收发器,满足LIN规范2.0,2.1和SAEJ2602-2, 工作电压5V-27V,完全兼容3.3V和5V器件,波特率高达20 Kbaud,并具有先进的EMI和ESD性能.本文介绍了ATA6663主要特性,方框图以及应用电路.

The ATA6663 is a fully integrated LIN transceiver complying with the LIN specification 2.0, 2.1 and SAEJ2602-2. The ATA6664 is an identical version, the only difference is that the TXD-dominant Time-out function is disabled so the device is able to send a static low signal to the LIN bus. 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 at up to 20 Kbaud with an RC oscillator for protocol handling. 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 ATA6663/ATA6664 feature advanced EMI and ESD performance.

ATA6663主要特性:

• Operating Range from 5V to 27V

• Baud Rate up to 20 Kbaud

• Improved Slew Rate Control According to LIN Specification 2.0, 2.1 and AEJ2602-2
