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; V
CC
voltage on) guarantee mini-
mized current consumption.
