1. Description

The ATA6622 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/50 mA output and a window watchdog. The ATA6624 has the same functionality

as the ATA6622; however, it uses a 5V/50 mA regulator. The ATA6626 has the same

functionality as ATA6624 without a TXD time-out timer. The voltage regulator is able

to source 50 mA, 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. ATA6622/ATA6624/ATA6626

are designed to handle the low-speed data communication in vehicles, e.g., in conve-

nience electronics. Improved slope control at the LIN-driver ensures secure data

communication up to 20 kBaud. Sleep Mode and Silent Mode guarantee very low cur-

rent consumption. The ATA6626 is able to switch the LIN unlimited to dominant level

via TXD for low data rates.
