1. 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). 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 mini-

mized current consumption.
