TLIN1024ARGYRQ1

Drivers, Receivers, Transceivers Overview

The TLIN1024ARGYRQ1 is a quad Local Interconnect Network (LIN) physical layer transceiver designed for automotive applications. It supports four independent LIN channels within a 24-pin VQFN package measuring 3.5 mm by 5.5 mm. The device operates with a supply voltage range of 4 V to 36 V and complies with LIN 2.0, 2.1, 2.2, 2.2A, and ISO/DIS 17987-4 standards. It features a transmit data rate up to 20 kbps and a receive data rate up to 100 kbps. Key electrical characteristics include ±45 V bus fault tolerance, integrated 45 kΩ pull-up resistors, and dominant state timeout protection.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and tape-and-reel specifications. Ensure the component meets AEC-Q100 Grade 1 qualification requirements for the intended automotive environment. Cross-reference the datasheet revision history to confirm compatibility with current design standards before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring four isolated LIN channels on a single node. The wide operating voltage range accommodates 12-V battery applications with transient conditions. Consider the integrated pull-up resistor and fault protection features to minimize external component count and simplify PCB layout constraints compared to standard transceivers lacking these integrations.

Drivers, Receivers, Transceivers Part Context

This part belongs to the Texas Instruments TLIN102xA-Q1 family of LIN transceivers. It shares functional similarities with the TLIN1022A-Q1 but provides four channels instead of two. The device is distinct from the TLIN1029-Q1, which offers a single channel. All variants in this series are designed for robust performance in harsh automotive electromagnetic environments.

Drivers, Receivers, Transceivers Replacement Considerations

The TLIN1024RGYTQ1 serves as a direct equivalent part number for the same quad LIN transceiver functionality. Designers should verify that any substitute maintains the required AEC-Q100 Grade 1 rating and compatible pinout configuration to ensure seamless integration without redesigning the host board.

Drivers, Receivers, Transceivers FAQ

How does the dominant state timeout feature function?

The dominant state timeout protection monitors the LIN bus for prolonged dominant states. If a dominant condition persists beyond the specified time limit, the device triggers a protective response to prevent potential bus lockups or damage.

What is the maximum receive data rate supported?

The receiver supports data rates up to 100 kbps, which facilitates faster in-line programming capabilities compared to standard LIN nodes limited to lower speeds.

Can the device be woken up from sleep mode?

Yes, the device supports wake-up events triggered either by activity on the LIN bus or by a local signal applied to the enable (EN) pin, allowing for flexible power management strategies.
