Description
ATA6629/ATA6631 is a fully integrated LIN transceiver, designed according to the LIN specification 2.0, 2.1 and SAEJ2602-2, 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.
