1. Description
The ATA6622 is a fully integrated LIN transceiver, which complies with the LIN 2.0
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 func-
tionality as ATA6624 without a TXD time-out timer. The voltage regulator is able to
source 50 mA up to VS = 18V. The output current of the regulator 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 communica-
tion in vehicles, e.g., in convenience electronics. Improved slope control at the
LIN-driver ensures secure data communication up to 20 kBaud. Sleep Mode and
Silent Mode guarantee very low current consumption. The ATA6626 is able to switch
the LIN unlimited to dominant level via TXD for low data rates.
