ATA6628

LIN Bus Transceiver with 3.3V (5V) Regulator and Watchdog

Atmel Corporation 

1. Description

The Atmel® ATA6628 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 3.3V/85mA output and a window watchdog. The Atmel ATA6630 has

the same functionality as the Atmel ATA6628; however, it uses a 5V/85mA regulator. The voltage regulator is able to source

up to 85mA, but the output current can be boosted by using an external NPN transistor. This chip combination makes it

possible to develop inexpensive, simple, yet powerful slave and master nodes for LIN-bus systems. Atmel

ATA6628/ATA6630 are 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. 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 short circuited LIN- bus.
