Atmel ATA663254汽车LIN网络解决方案

Atmel公司的ATA663254是全集成的LIN收发器,设计满足LIN标准2.0, 2.1, 2.2, 2.2A和 SAEJ2602-2,并集成了低压降的5V/85mA稳压器,电源电压高达40V,工作电压5V-28V,睡眠模式电流9uA.本文介绍了ATA663254主要特性,框图和典型应用电路,以及评估板ATAB663254A-V1.2主要特性,电路图,材料清单和PCB布局图.

The Atmel® ATA663254 system basis chip is a fully integrated LIN transceiver, designed according to the LIN specification 2.0, 2.1, 2.2, 2.2A and SAEJ2602-2, with a low-drop voltage regulator 5V/85mA. The combination of voltage regulator and bus transceiver makes it possible to develop simple but powerful slave nodes in LIN bus systems. Atmel ATA663254 is designed to handle the low-speed data communication in vehicles (for example, in convenience electronics). Improved slope control at the LIN driver ensures secure data communication up to 20Kbaud. The bus output is designed to withstand high voltage. Sleep mode and silent mode guarantee minimized current consumption even in the case of a floating or a shorted LIN bus.
