Description The 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/50 mA output and a window watchdog. The ATA6630 has the same functionality as the ATA6628; however, it uses a 5V/50 mA regulator. 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. ATA6628/ATA6630 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.
