Description

The Atmel^®ATA6630 is a fully integrated LIN transceiver, which complies with the LIN 2.0, 2.1 and SAEJ2602-2

specifications. It has a low-drop voltage regulator for 5V/85mA output and a window watchdog. The voltage regulator is able

to source up to 85mA, but the output current can be boosted by using an external NPN transistor. The Atmel ATA6630 is

designed to handle the low-speed data communication in vehicles, e.g., in convenience electronics. Improved slope control

at the LIN-driver ensures secure data communication up to 20kBaud. Sleep Mode and Silent Mode guarantee very low

current consumption.
