ATA6623C-TAQY Datasheet PDF - ATMEL

●Description

●ATA6623/ATA6625 is a fully integrated LIN transceiver, designed according to the LIN specification 2.0 and 2.1, with a low-drop voltage regulator (3.3V/5V/50 mA). The combination of voltage regulator and bus transceiver makes it possible to develop simple, but powerful, slave nodes in LIN Bus systems. ATA6623/ATA6625 is designed to handle the low-speed data communication in vehicles (for example, in convenience electronics).
