TJA1441AT/0Z

Drivers, Receivers, Transceivers Overview

The TJA1441AT/0Z is a high-speed CAN transceiver from the TJA144x family, designed to interface between a CAN or CAN FD protocol controller and the physical two-wire bus. It complies with ISO 11898-2:2016 and SAE J2284 standards, supporting data rates up to 5 Mbit/s for both Classical CAN and CAN FD fast phases. The device operates within a supply voltage range of 4.5 V to 5.5 V on pin VCC and features an additional VIO supply pin (2.95 V to 5.5 V) for I/O level adaptation. It supports Normal and Silent modes, includes undervoltage detection, and offers ESD protection of 8 kV. The component is qualified according to AEC-Q100 Grade 1 and is available in SO8 and HVSON8 packages.

Drivers, Receivers, Transceivers Feature Summary

• Supports standard CAN and CAN FD data bit rates up to 5 Mbit/s
• Features low electromagnetic emission and high electromagnetic immunity
• Includes undervoltage detection with defined fail-safe behavior
• Provides internal biasing of TXD and mode selection input pins

Drivers, Receivers, Transceivers Applications

• High-speed Classical CAN network nodes
• CAN FD network nodes requiring reliable communication at 5 Mbit/s
• Automotive electronic control units (ECUs)
• Industrial applications requiring robust CAN physical layer interfaces

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix matches the required package type, as the TJA1441 series includes variants such as AT (SO8), ATK (HVSON8), BT, BTK, DT, and DTK. Confirm that the TJA1441A variant with the VIO pin is selected if interfacing with 3.3 V microcontrollers is necessary. Ensure compliance with RoHS and halogen-free requirements by checking the product status documentation provided by NXP Semiconductors.

Drivers, Receivers, Transceivers Selection Notes

Select the TJA1441AT/0Z when a high-speed CAN transceiver with a separate VIO supply pin is required for direct interfacing with 3.3 V or 5 V microcontrollers without additional logic. This variant is suitable for designs needing pin compatibility with legacy parts like the TJA1051 while offering improved EMC performance. Consider the HVSON8 package if enhanced thermal performance and automated optical inspection capabilities are prioritized over the standard SO8 package.

Drivers, Receivers, Transceivers Part Context

The TJA1441AT/0Z belongs to the TJA144x family of high-speed CAN transceivers manufactured by NXP Semiconductors. This family is designed to provide a simple replacement for older high-speed transceivers, ensuring interoperability with existing hardware and software designs. The TJA1441A variant specifically adds the VIO pin to support flexible I/O levels, distinguishing it from the TJA1441B which lacks this feature.

Drivers, Receivers, Transceivers Replacement Considerations

The TJA1441 is designed as a pin-compatible replacement for the TJA1051 and TJA1057. When substituting these parts, verify that the application does not require the Standby or Sleep modes present in other TJA144x variants but absent in the TJA1441A.
