• Master and Slave Operation Possible
• Supply Voltage up to 40V
• Operating voltage VS = 5V to 27V
• Typically 10µA Supply Current During Sleep Mode
• Typically 57µA Supply Current in Silent Mode
• Linear Low-drop Voltage Regulator, 85mA Current Capability:

The ATA6622 is a fully integrated LIN transceiver, which complies with the LIN and SAEJ2602-2 specifications. It has a low-drop voltage regulator for 3.3V/85mA output and a window watchdog. The Atmel ATA6624 has the same functionality as the Atmel ATA6622 however, it uses a 5V/85mA regulator. The Atmel ATA6626 has the same functionality as Atmel ATA6624 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 ATA6622/ATA6624/ATA6626 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 ATA6626 is able to switch the LIN unlimited to dominant level via TXD for low data rates.
