Description

ATA6620 is a fully integrated LIN transceiver, designed according to the LIN specification 2.0, with a low-drop voltage regulator (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. ATA6620 is designed to handle the low-speed data communication in vehicles (for example, inconvenience electronics).
