TJA1441ATK/0Z - 5 Mbps CAN FD Transceiver | NXP
料号： TJA1441ATK/0Z ✓ 量产中TJA1441ATK/0Z 概述
A CAN transceiver, also called a CAN bus interface or CAN controller interface, is the physical-layer component that connects a host controller or microcontroller to a differential CAN network. It converts logic-level signaling into the differential bus waveform and receives bus information back as digital logic. The TJA1441 family combines a CAN transmitter and receiver in one package, reducing component count while preserving compatibility with established CAN hardware.
The principal benefits of the TJA1441ATK/0Z are its support for CAN FD, its 5 Mbps maximum data rate, and its Silent mode. Silent mode allows the transmitter to be disabled while the receiver continues monitoring bus activity, which is useful in power-management and bus-management arrangements. NXP describes the family as a straightforward replacement for high-speed Classical CAN and CAN FD transceivers such as the TJA1051 and TJA1057, with pin compatibility intended to reduce hardware and software changes during retrofit work.
The TJA1441ATK/0Z is a half-duplex interface with one transmitter and one receiver. Its 8-HVSON package is intended for surface-mount assembly and tape-and-reel production. The specified operating range extends from -40 °C to 150 °C junction temperature, supporting industrial and automotive environments where temperature, EMI behavior, and dependable bus operation are important.
Typical uses include automotive body and comfort electronics, industrial automation equipment, embedded control systems, CAN-based diagnostics, and retrofit platforms that previously used compatible NXP transceivers. The small 3 mm by 3 mm package also helps reduce board area beside tightly spaced microcontrollers, transceivers, and power-management components.
When laying out the device, follow the manufacturer datasheet for CANH, CANL, VCC, ground, mode-control, RXD, and exposed-pad connections. Preserve the recommended termination and common-mode network implementation, and keep high-current bus paths compact. Validate silent-mode polarity and external transceiver logic against the host firmware before using the part for wake-up or redundant-bus arrangements.
This product page combines the manufacturer specification with practical guidance for package selection, CAN bus integration, thermal and PCB considerations, qualification status, and drop-in replacement evaluation. It is intended to help engineers compare the TJA1441ATK/0Z against established NXP CAN interfaces before committing a board revision.

典型应用
TJA1441ATK/0Z 适用于 6 应用s: Automotive Body and Comfort Control, Industrial Automation CAN FD Gateway, CAN FD Diagnostics Interface, Embedded Machinery Sensor Network, Retrofit of Existing CAN Designs, Low-Power Bus Monitoring Node.
Automotive Body and Comfort Control
The TJA1441ATK/0Z suits automotive body and comfort-control nodes that exchange Classical CAN messages while also benefiting from CAN FD-capable controllers. Its 4.5 V to 5.5 V operating range supports regulated 5 V digital rails, and its 5 Mbps capability provides headroom for fast control and diagnostic traffic. The one-transmitter, one-receiver half-duplex arrangement fits centralized vehicle networks. NXP identifies the series as automotive and AEC-Q100, while the -40 °C to 150 °C junction-temperature range supports demanding thermal environments. Final qualification still requires system-level EMC, fault, and environmental validation.
推荐
Industrial Automation CAN FD Gateway
The TJA1441ATK/0Z is appropriate for an industrial gateway that bridges a host processor to a CAN FD field network. Its 5 Mbps interface rate supports faster payload transfer than Classical CAN while retaining compatibility with conventional CAN nodes. The 4.5 V to 5.5 V supply range aligns with common 5 V equipment rails, and Silent mode helps a gateway monitor traffic without continuously driving the bus. The compact 8-HVSON, 3 mm by 3 mm package saves board space beside dense controllers. Designers should still validate termination, fault behavior, isolation strategy, and electromagnetic compatibility for the installed enclosure and cable environment.
推荐
CAN FD Diagnostics Interface
The TJA1441ATK/0Z can form the physical-layer endpoint of a CAN FD diagnostics adapter connected to a host controller. A 5 Mbps maximum data rate allows the adapter to handle diagnostic sessions more efficiently than a Classical CAN-only link, while the 4.5 V to 5.5 V range simplifies connection to regulated 5 V logic. Its receive output supports host monitoring, and Silent mode can reduce unwanted bus activity during selected operating states. Board implementation must follow the manufacturer pin and layout guidance, preserve recommended bus termination, and provide protection appropriate to the length and environment of the diagnostic harness.
推荐
Embedded Machinery Sensor Network
The TJA1441ATK/0Z fits compact embedded controllers used in machinery for sensor polling, actuator commands, and status reporting over CAN. Its CAN FD capability provides higher throughput when nodes exchange multi-payload diagnostic or configuration records, and its 5 Mbps ceiling leaves performance margin for a well-designed network. The 3 mm by 3 mm 8-HVSON package reduces footprint pressure beside a microcontroller and signal-conditioning circuits. Silent mode can support coordinated bus management. Engineers should evaluate bus length, node count, termination placement, common-mode voltage, isolation requirements, and conducted-noise immunity before approving a machine installation.
推荐
Retrofit of Existing CAN Designs
The TJA1441 family is specifically intended to simplify retrofits of existing high-speed Classical CAN and CAN FD transceivers such as the TJA1051 and TJA1057. NXP states that pin compatibility is designed to avoid changes to hardware and software, making the TJA1441ATK/0Z useful when a refresh requires CAN FD capability, Silent mode, or a more compact package. A retrofit must still verify the physical footprint and package height, controller interface levels, mode-control wiring, bus timing, and thermal environment. The manufacturer wording establishes design intent but does not make every circuit board automatically interchangeable.
推荐
Low-Power Bus Monitoring Node
The TJA1441ATK/0Z can support a monitoring node that must observe CAN traffic while limiting interference with the bus. Silent mode is the defining feature for this use because it supports a receive-oriented operating mode without the transceiver functioning as the normal active transmitter. Its 5 Mbps capability is more than adequate for diagnostic observation and short control frames, while the compact 8-HVSON package suits space-constrained monitoring equipment. The host design must configure the mode-control signal correctly, account for RXD behavior in the selected state, and maintain supply decoupling and bus termination according to the manufacturer layout guidance.

关键差异点
- Supports both Classical CAN and CAN FD in one physical-layer interface （对比 TJA1051)
- Provides a dedicated Silent-mode operating option （对比 TJA1057)
- Uses a compact surface-mount 8-HVSON package （对比 TJA1442ATK/S1Z)
设计说明
Use the NXP TJA1441 land pattern and exposed-pad connection exactly as specified in the manufacturer datasheet. Place the transceiver close to the CANH and CANL interface entry, keep the differential pair geometry compact and symmetric, and minimize the loop area between the pins and bus connector. Route the pair away from switching nodes and unrelated high-current paths. The small 8-HVSON footprint reduces routing space, so pad escape geometry and assembly clearances should be checked before releasing the PCB artwork.
Do not assume that all TJA1441 ordering codes are interchangeable solely because they share the TJA1441ATK base name. TJA1441ATK/0Z and TJA1441ATK/S1Z appear in cross-reference records with different suffixes, but the available documentation does not define every commercial or qualification distinction. For a production substitution, compare the exact ordering table, pin functions, electrical characteristics, qualification statement, date-code rules, and lifecycle commitment. Also verify mode-control polarity because incorrect firmware or wiring can prevent the intended Silent-mode operation.
Place the required 5 V supply decoupling capacitors at the VCC and ground pins using the placement and capacitance values specified by NXP. Keep the supply return path short and connect the exposed pad according to the manufacturer package guidance. In a vehicle or industrial installation, account for supply transients, ground offset, bus faults, and EMI coupling rather than relying only on nominal 5 V operation. Verify that the host controller and transceiver interface levels match and that the power source remains within the 4.5 V to 5.5 V supply range.
The specified operating range extends to 150 °C junction temperature, so thermal analysis must include maximum ambient temperature, local heating, copper area, and the package's exposed-pad heat-flow path. Use the manufacturer thermal characterization data for final calculations. Place the device where airflow or board copper can remove heat as effectively as the enclosure allows, and avoid placing a hot regulator or power stage directly beside the CAN transceiver. Validate worst-case conditions because a compliant bus interface can still fail if its junction-temperature margin is insufficient.
