ATA6624C
1. Description
The Atmel® ATA6622C 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 ATA6624C has
the same functionality as the Atmel ATA6622C; however, it uses a 5V/85mA regulator. The Atmel ATA6626C has the same
functionality as Atmel ATA6624C without a TXD time-out timer. The voltage regulator is able to source 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 ATA6622C/ATA6624C/ATA6626C 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. Sleep Mode and Silent Mode guarantee very low current
consumption. The Atmel ATA6626C is able to switch the LIN unlimited to dominant level via TXD for low data rates.
