MCHPATA663211-GAQW
Overview
The ATA663211-GAQW is a standalone LIN transceiver designed for automotive and industrial communication, providing the interface between a protocol controller and the physical LIN bus. It supports bit rates up to 20 Kbaud and features advanced EMC and ESD performance for harsh environments. This AEC-Q100 qualified device includes a wide supply voltage range from 5V to 28V and integrated wake-up logic.
Why Choose This Part
This transceiver offers an extremely low sleep current of 9 uA and features wake-up source recognition to help identify if the bus or a local pin triggered the system. It includes comprehensive protection against short circuits to battery or ground and incorporates a TXD time-out timer to prevent bus locking.
Applications
Key Specifications
Getting Started
To evaluate the ATA663211-GAQW, engineers can utilize Microchip's automotive networking development boards or implement the 8-SOIC package on a custom carrier for breadboarding. Ensure the INH pin is properly configured to manage external system regulators, and verify that the LIN bus pull-up resistor (typically 1k for Master nodes or 30k for Slave nodes) is correctly populated.
