TJA1441DTK/0Z - 5 Mbit/s CAN FD Transceiver | NXP
MPN： TJA1441DTK/0Z ✓ 啟用中TJA1441DTK/0Z 概覽
A CAN transceiver is an interface IC within the broader CAN controller-to-bus communication path. It converts logic-level TXD and RXD signals into the physical voltages and currents used on a differential CAN bus, while receiving bus signals and presenting a compatible logic output to the protocol controller. This electrical boundary helps isolate the controller from the physical bus while supporting bidirectional communication over a two-wire network.
The TJA1441 is intended for high-speed embedded CAN and CAN FD networks, including automotive electronics, industrial automation, robotics, vehicle networking, and embedded control systems. Its principal feature is support for CAN FD data rates up to 5 Mbit/s. Silent mode allows the transceiver to monitor reception without driving the bus actively, while selectable Off mode provides a low-power operating state for power-management and parked-system requirements.
The 8-pin HVSON package uses a compact surface-mount format suited to space-constrained controller boards. NXP describes the device as a drop-in option for compatible high-speed transceivers, helping existing designs retain their PCB layout and software architecture. Migration still requires verification of pin functions, supply requirements, bus timing, mode-control logic, and transceiver operating characteristics before production release.
Typical deployments include CAN FD gateways, vehicle body-control modules, industrial motor controllers, robotic communication networks, diagnostic equipment, and distributed sensor systems. In each application, the transceiver connects a local CAN protocol controller to the bus while providing bus-side fault handling and local mode control.
Design the PCB around the exact 8-pin HVSON footprint, exposed thermal-pad requirements, input and output capacitor requirements, bus termination network, and common-mode choke or split-termination solution identified in the manufacturer datasheet. Keep the CAN_H and CAN_L routing symmetrical, minimize stub lengths, and provide a continuous return path beneath the bus pair to reduce radiated emissions and susceptibility to electromagnetic interference.
This product page consolidates manufacturer documentation, package information, lifecycle status, drop-in migration candidates, comparison points, and application-specific design guidance. It also distinguishes documented replacement options from parts that may have similar functions but do not share the required package and pin compatibility.

典型應用
TJA1441DTK/0Z 適用於 6 應用s: Automotive CAN FD Gateway, Industrial Automation Network, Robotics Controller Interface, Vehicle Network Interface, CAN FD Diagnostic Adapter, Distributed Sensor Network.
Automotive CAN FD Gateway
The TJA1441DTK/0Z fits an automotive CAN FD gateway that translates between a host controller and a two-wire vehicle network. Its confirmed CAN FD capability extends to 5 Mbit/s, allowing high-rate payload traffic while retaining compatibility with Classical CAN nodes. Silent mode is useful when the gateway must monitor bus activity without actively driving the network, and selectable Off mode can support controlled power states. Place the device near the bus connector, preserve a symmetrical CAN_H/CAN_L route, and validate transient, temperature, and qualification requirements against the ordered variant before production use.
推薦
Industrial Automation Network
The TJA1441DTK/0Z can serve as the physical-layer interface in industrial automation equipment that connects a local controller to a two-wire CAN bus. Support for CAN FD data rates up to 5 Mbit/s benefits equipment combining control traffic with larger diagnostic or data-transfer payloads. Silent mode provides a path for passive monitoring in redundant or diagnostic arrangements. The compact 8-pin HVSON package also helps minimize board area in distributed I/O modules. Validate bus timing, termination, common-mode behavior, and industrial environmental requirements before integrating it into production machinery.
推薦
Robotics Controller Interface
Robotic arms, mobile robots, and coordinated motion systems can use the TJA1441DTK/0Z to connect a motion or safety controller to CAN-connected actuators and sensors. The 5 Mbit/s CAN FD capability supports a broader mix of real-time control and payload traffic than a Classical CAN-only network. The device's compact 3 mm by 3 mm HVSON package is useful where controller boards are densely populated. Keep the bus pair tightly coupled, place termination according to the manufacturer circuit, and confirm electromagnetic compatibility when robot systems contain motor drives and long cable runs.
推薦
Vehicle Network Interface
The TJA1441DTK/0Z is appropriate for a vehicle network interface module that translates controller logic to the physical CAN bus. Its confirmed operation up to 5 Mbit/s supports CAN FD traffic while maintaining a straightforward path to Classical CAN devices. Silent mode supports listen-only diagnostics, while Off mode can be coordinated with vehicle power management. For an automotive design, confirm the exact part's temperature range, transient protection, ESD rating, and AEC-Q100 status in the manufacturer documentation. Use short, symmetric bus routing and appropriate bus-side filtering for reliable EMC performance.
推薦
CAN FD Diagnostic Adapter
A portable or bench-mounted CAN FD diagnostic adapter can use the TJA1441DTK/0Z to connect a computer or embedded tester to an external vehicle or industrial bus. Operation up to 5 Mbit/s permits faster diagnostics than Classical CAN, while Silent mode enables passive monitoring without intentionally affecting bus traffic. The small 8-pin HVSON footprint supports compact multi-channel adapters. Keep the connector-to-transceiver trace short, use a chassis-ground strategy appropriate to the adapter, and validate the external bus and cable environment to avoid ground-loop problems or unintended bus activity.
推薦
Distributed Sensor Network
The TJA1441DTK/0Z can connect a local edge controller to distributed sensors over a two-wire CAN network. A 5 Mbit/s CAN FD link provides sufficient bandwidth for sensor configuration, diagnostics, and status information while accommodating larger diagnostic payloads. Silent mode is useful when multiple nodes must monitor the same bus, and the compact HVSON package fits densely populated sensor-hub boards. For long cables or noisy industrial environments, evaluate common-mode filtering, termination placement, grounding, and protection devices against the manufacturer recommendations.

主要差異化特點
- Combines 5 Mbit/s CAN FD operation with Silent and selectable Off modes (對比TJA1442DTK/0Z)
- Uses the same compact HVSON family format as the closest migration candidates (對比TJA1443DTK/0Z)
- Supported as a retrofit path for established high-speed CAN designs (對比TJA1051)
設計說明
Use the exact 8-pin HVSON footprint and thermal-pad geometry defined in the NXP TJA1441 datasheet rather than adapting a generic SOIC-8 land pattern. Keep CAN_H and CAN_L on one layer as a tightly coupled pair with matching geometry, minimize vias and stubs, and maintain a continuous ground reference below the pair. Place the transceiver close to the bus connector so the unfiltered bus-side path remains short.
A CAN bus is a physical-layer interface as well as a digital communication link. Follow the manufacturer recommendations for bus termination, common-mode choke or split termination, external protection, and grounding. Route the pair away from switching nodes and clocks, use a solid ground plane, and verify radiated and immunity performance in the final enclosure and cable configuration. Do not treat a generic termination value as a substitute for the complete recommended circuit.
Confirm that software mode control matches the selected transceiver because Silent, standby, Off, and normal operation determine whether the device drives the bus. Before retrofitting TJA1441 into a TJA1051 or TJA1057 design, compare every pin, exposed-pad connection, supply range, mode-control level, bus timing, and wake-up behavior. A same-footprint appearance alone is not sufficient evidence of an unconditional drop-in replacement.
