ATA663211-GAQW

Drivers, Receivers, Transceivers Overview

The ATA663211-GAQW is a fully integrated LIN transceiver compliant with LIN specifications 2.0, 2.1, 2.2, 2.2A and SAEJ2602-2. It operates within a supply voltage range of 5V to 28V, with an absolute maximum rating of 40V. The device supports data communication up to 20 Kbaud with improved slope control. Supply current consumption is typically 9 µA in Sleep mode, 80 µA in Fail-Safe mode, and 250 µA in Normal mode. It features wake-up capability through the LIN bus or external WKin pin, both requiring a minimum pulse duration of 100 µs. The component includes overtemperature and short-circuit protection for the bus pins against GND and battery connections.
