TJA1044VTK/3Z - High-Speed CAN Transceiver in 8-HVSON
MPN: TJA1044VTK/3Z ✗ Akhir HayatTJA1044VTK/3Z Ringkasan
A CAN transceiver is a physical-layer interface integrated circuit that converts logic-level signals from a CAN controller into differential bus voltages and converts differential bus levels back into logic-level receive signals. The CAN hierarchy connects a microcontroller or dedicated CAN controller through a high-speed CAN transceiver to a robust two-wire network. This separation allows the controller to manage frames, arbitration, error handling, and higher-level protocols while the transceiver handles signal levels and bus dominance.
The TJA1044VTK/3Z combines a half-duplex CAN transmitter and receiver in one device. Its differential bus interface supports the high-speed CAN physical layer, while standby mode provides a control path for reducing activity when the node is not communicating. VeLIO certification is identified for this device family, reflecting compatibility requirements for high-speed CAN communication. The compact 8-HVSON package supports surface-mount assembly on space-constrained automotive and industrial controller boards.
Because the TJA1044V belongs to the Mantis transceiver family, its architecture is centered on dependable CAN bus operation and controller-to-bus signal conversion. The integrated receive and transmit paths simplify the physical-layer design around a CAN controller. The 3 mm by 3 mm package also reduces board area, although its exposed-pad construction and exposed-pad construction requires correct land-pattern, solder, and thermal practices to achieve reliable assembly.
Typical uses include automotive body and comfort modules, industrial automation controllers, gateway equipment, embedded CAN nodes, and transport systems. The device is especially appropriate when a compact CAN interface is required alongside a microcontroller or CAN controller. Board-level implementation must include the required bus termination, decoupling, protection strategy, and transceiver-controller interface defined by the manufacturer application guidance.
Designers should verify the exact CAN controller voltage, logic levels, standby polarity, pin mapping, and supply requirements before finalizing the PCB. For a new layout, follow the NXP TJA1044V datasheet land pattern and application circuit rather than deriving an HVSON footprint from package dimensions alone. PCB review should also include exposed-pad soldering, return-path continuity, bus stubs, and protection-component placement.

Aplikasi Biasa
TJA1044VTK/3Z patut untuk 6 aplikasis: Automotive Body Control Module, Industrial Automation Controller, Embedded CAN Gateway, Transport and Rail Equipment, CAN Communication Module, Test and Measurement Equipment.
Automotive Body Control Module
The TJA1044VTK/3Z fits an automotive body-control module that connects a CAN controller to a high-speed two-wire vehicle network. Its 1/1 half-duplex transceiver arrangement provides differential transmit and receive functions, while standby mode helps the controller manage node activity. The compact 8-HVSON, 3 mm by 3 mm package conserves PCB area in densely populated body electronics. Automotive qualification also requires checking the exact ordering-code temperature range, EMC performance, and system-level protection requirements before release.

Industrial Automation Controller
The TJA1044VTK/3Z is suitable for an industrial automation controller that must exchange command, status, and diagnostic frames over a high-speed CAN bus. Its differential physical interface supports communication between a CAN controller and a two-wire network, while the standby function provides a way to manage low-activity operating states. The surface-mount 8-HVSON package supports compact control boards, but the finished design still needs suitable surge and ESD protection, chassis-grounding strategy, and immunity validation for the installation environment.
Disebarkan
Embedded CAN Gateway
The TJA1044VTK/3Z can serve as the physical-layer element in an embedded CAN gateway that translates or routes traffic between a host processor and an external high-speed CAN network. Its one-transmitter, one-receiver configuration maps directly to a conventional CAN controller interface and avoids allocating separate discrete bus drivers and receivers. The 3 mm by 3 mm HVSON package is valuable in gateways that also include Ethernet, memory, and power-management circuitry. Firmware must handle bus-off recovery, error counters, and standby-state transitions at the controller level.
Disebarkan
Transport and Rail Equipment
The TJA1044VTK/3Z is appropriate for transport equipment nodes that use high-speed CAN for distributed control and diagnostics. Its differential two-wire interface supports reliable signaling over a shared network, and standby mode allows a node to reduce transceiver activity when normal communication is not required. The compact surface-mount package supports dense controller assemblies. For rail or transport equipment, confirm the exact temperature grade, electromagnetic compatibility requirements, isolation strategy, bus protection, and diagnostic behavior required by the vehicle or system specification.

CAN Communication Module
The TJA1044VTK/3Z is a strong fit for a dedicated CAN communication module that exposes a standardized bus connector to sensors, actuators, or test equipment. Its 1/1 transceiver arrangement handles differential bus transmission and reception, while standby mode supports controlled module states. The small 8-HVSON footprint leaves room for connector protection, isolated power, and status indicators. The module designer should use the NXP application guidance to select termination, common-mode choke, protection devices, and layout features that preserve signal quality and fault containment.
Disebarkan
Test and Measurement Equipment
The TJA1044VTK/3Z can be used in CAN test equipment, diagnostic fixtures, and communication analyzers that need to connect a controller or instrument to a high-speed CAN bus. The device provides a compact differential physical-layer endpoint with receive and transmit functions in one package. Its standby mode assists power-state management in portable or intermittent test systems. Instrument designers should account for high common-mode voltages, bus faults, ESD exposure, and the difference between nominal network termination and analyzer connection requirements when planning protection and test access.

Catatan Desain
Use the land pattern, exposed-pad dimensions, and solder recommendations in the NXP TJA1044V manufacturer datasheet rather than constructing an HVSON footprint from the 3 mm by 3 mm body size. Keep the CAN bus pins and their protection components away from long, high-current return paths. Provide a continuous ground reference beneath the device and route CAN_H and CAN_L as a closely coupled differential pair away from switching nodes and noisy clocks.
Do not confuse conventional high-speed CAN with CAN FD when selecting this transceiver. The TJA1044VTK/3Z is identified as a high-speed CAN device, whereas a separate TJA1044DTK family member is described as CAN FD capable. Also verify whether the selected termination strategy uses two split resistors or a single termination component. Incorrect termination, excessive stubs, and poorly grounded connectors can create reflections that are not solved by changing the transceiver itself.
Place CAN-bus protection devices close to the external connector, and keep the protected path between the connector and transceiver short. This limits the length of unprotected cable-stub area that can receive ESD or surge events. Select protection components that are appropriate for the bus voltage and data rate, and provide a low-impedance chassis or signal-ground return according to the vehicle or industrial installation requirements. Validate EMC performance at the finished enclosure and cable configuration.
Differentiate CAN_H and CAN_L consistently from the CAN controller through the transceiver and protection network. Maintain symmetry where practical, use a solid ground plane, and avoid introducing unnecessary vias or test-probe stubs on the bus. Check receiver and standby levels against the connected controller voltage. If radiated emissions or bus-integrity measurements show problems, investigate common-mode choke placement and return-current paths before changing software timing or termination values.
