TJA1441ATK/0Z

Drivers, Receivers, Transceivers Overview

The TJA1441ATK/0Z is a high-speed CAN transceiver from the TJA144x family, designed to interface between a CAN or CAN FD controller and the physical two-wire bus. It complies with ISO 11898-2:2016 and supports data rates up to 5 Mbit/s in Normal and Silent modes. The device operates on a single VCC supply of 4.5 V to 5.5 V, drawing typical currents of 38 mA (dominant) and 4 mA (recessive). It features an HVSON8 package, 8 kV ESD protection, and undervoltage detection thresholds at 4 V to 4.5 V.

Drivers, Receivers, Transceivers Feature Summary

• Supports standard CAN and CAN FD protocols with data rates up to 5 Mbit/s
• Provides silent mode for node diagnosis and failure containment
• Includes TXD dominant time-out function to prevent permanent bus blocking
• Features internal biasing of control pins for defined fail-safe behavior

Drivers, Receivers, Transceivers Applications

• Automotive CAN networks requiring high-speed communication
• Industrial applications needing robust CAN FD interfaces
• Systems requiring silent mode for network diagnostics

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and variant features. Ensure compatibility with existing hardware designs when replacing legacy transceivers like the TJA1051 or TJA1057. Confirm that the HVSON8 package footprint matches the target PCB layout requirements.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring pin-compatible upgrades to older high-speed CAN transceivers. The TJA1441A variant includes a VIO pin for direct interfacing with 3.3 V microcontrollers, whereas the TJA1441B variant relies solely on the VCC supply. Consider the thermal resistance characteristics of the HVSON8 package for heat dissipation needs.

Drivers, Receivers, Transceivers Part Context

This part belongs to the TJA144x family of high-speed CAN transceivers. Variants include the TJA1441A with a VIO pin, the TJA1441B without it, and the TJA1441D with an Off mode input. An AEC-Q100 Grade 0 version (TJR1441) is available for higher temperature operation.

Drivers, Receivers, Transceivers Replacement Considerations

Publicly confirmed pin-compatible replacements include the TJA1051 and TJA1057 from NXP Semiconductors.
