The ATA6620N is a single-chip LIN transceiver designed by Atmel (now Microchip Technology). This device facilitates communication in automotive and industrial applications using the Local Interconnect Network (LIN) protocol. It integrates a LIN transceiver, voltage regulator, and microcontroller interface, offering a compact solution for LIN-based systems.

Applications:

• Automotive Body Control Systems (e.g., window lift, door lock)
• Automotive Sensor Networks
• Industrial Automation
• HVAC Systems
• Lighting Control Systems

Features:

• LIN 2.1 and SAE J2602 compliant transceiver.
• Integrated voltage regulator for microcontroller supply.
• Low power consumption in sleep mode.
• Overvoltage and short-circuit protection.
• Microcontroller interface for data transmission and reception.

Benefits:

• Enables reliable communication in LIN networks.
• Reduces the number of external components required.
• Improves system energy efficiency.
• Protects the system from electrical faults.
• Simplifies the design of LIN-based applications.

Additional Details:

The ATA6620N operates with a single power supply and supports LIN communication speeds up to 20 kbps. It provides a physical layer interface for LIN communication, allowing microcontrollers to communicate with other devices on the network. Detailed information on electrical characteristics, timing diagrams, and application circuits can be found in the Atmel datasheet for the ATA6620N.
