1. Description
ATA6623/ATA6625 is a fully integrated LIN transceiver, designed according to the LIN
specification 2.0, 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 pow-
erful, slave nodes in LIN Bus systems. ATA6623/ATA6625 is designed to handle the
low-speed data communication in vehicles (for example, in convenience electronics).
Improved slope control at the LIN driver ensures secure data communication up to
20 kBaud with an RC oscillator for the protocol handling. The bus output is designed
to withstand high voltage. Sleep Mode (voltage regulator switched off) and Silent
Mode (communication off; VCC voltage on) guarantee minimized current consumption.
