TJA1442BTK/0Z - 5 Mbit/s CAN FD Transceiver | NXP
MPN： TJA1442BTK/0Z ✓ 啟用中TJA1442BTK/0Z 概覽
A CAN transceiver is an interface IC that converts logic-level signals from a CAN controller into the differential electrical signaling used on a CAN bus, while converting received bus signals back into controller-compatible logic. The TJA144x family belongs to the broader hierarchy of CAN interface ICs, network interface ICs, interface semiconductors, and communication semiconductors. Its CAN FD capability supports higher-bandwidth automotive and industrial networks while retaining compatibility with conventional CAN systems.
The TJA1442BTK/0Z includes a standby operating mode for systems that need to reduce activity when the communication network is not in use. The manufacturer positions the TJA1442 as a straightforward replacement for existing high-speed Classical CAN and CAN FD transceivers, including the NXP TJA1042 and TJA1044GT families. This replacement positioning helps support design updates and retrofit applications without changing the surrounding hardware and software architecture.
The device is suitable for automotive electronic control units, battery-management systems, charging equipment, industrial automation controllers, robotics, building automation, and embedded CAN FD gateways. Its small 3 x 3 mm HVSON footprint is useful for compact control boards where component placement, routing, and thermal management must be carefully controlled.
For new designs, confirm the controller voltage levels, bus termination strategy, transceiver mode-control requirements, and the exposed-pad soldering recommendations in the manufacturer datasheet. In retrofit designs, verify that every pin function and supply reference matches the original transceiver before substituting the TJA1442BTK/0Z.
This product page combines the manufacturer’s device positioning, package information, CAN FD speed capability, replacement context, and practical design guidance to support component selection, footprint review, and PCB integration.

典型應用
TJA1442BTK/0Z 適用於 6 應用s: Automotive CAN FD Electronic Control Units, Battery Management Systems, EV Charging and Power Distribution, Industrial Automation and Robotics, Building Automation and HVAC Networks, Industrial Sensor and Gateway Hubs.
Automotive CAN FD Electronic Control Units
The TJA1442BTK/0Z fits automotive electronic control units that exchange control and diagnostic data over a two-wire CAN FD network. Its support for CAN FD fast-phase rates up to 5 Mbit/s provides additional bandwidth compared with Classical CAN while retaining compatibility with CAN protocols. The 8-HVSON, 3 x 3 mm package also supports compact controller-board layouts. Final automotive use requires confirmation of the exact ordering code, environmental qualification, temperature grade, and production requirements.
推薦
Battery Management Systems
The TJA1442BTK/0Z can connect a battery-management controller to a vehicle CAN FD network for cell-monitoring data, diagnostics, and power-system commands. Supporting communication up to 5 Mbit/s helps the management system exchange higher volumes of sensor and status information during normal operation. Its small 8-HVSON footprint leaves more board area for protection, sensing, and power-conversion circuitry. The board design must provide the supply rails, mode-control logic, CAN termination, and grounding required by the transceiver.
推薦
EV Charging and Power Distribution
The TJA1442BTK/0Z is appropriate for charging controllers and power-distribution modules that use CAN FD to coordinate system state, available power, fault information, and operating commands. A 5 Mbit/s CAN FD fast-phase rate supports efficient controller-to-node communication, while standby mode can assist systems that manage activity around charging sessions. Designers should confirm wake-up behavior, bus bias, termination, isolation strategy, and the electrical limits that apply to the intended vehicle or charger platform.
推薦
Industrial Automation and Robotics
The TJA1442BTK/0Z can serve as the physical-layer interface for industrial automation and robotics controllers that use CAN FD for machine commands and sensor feedback. The transceiver handles communication between the protocol controller and the two-wire bus at rates up to 5 Mbit/s in the CAN FD fast phase. Its compact 3 x 3 mm 8-HVSON package is advantageous in space-constrained control modules. Bus segmentation, common-mode range, grounding, and termination must be engineered for the installation environment.
推薦
Building Automation and HVAC Networks
The TJA1442BTK/0Z supports building-control nodes that need a compact interface for CAN FD communication between room controllers, sensors, actuators, and supervisory equipment. CAN FD data rates up to 5 Mbit/s can accommodate combined control and diagnostic traffic on a two-wire network. The standby function is useful when subsystem managers need to manage transceiver activity, but wake-up and sleep transitions must be coordinated with the CAN controller. Proper bus termination and reference-ground implementation are essential in distributed building installations.
推薦
Industrial Sensor and Gateway Hubs
The TJA1442BTK/0Z can bridge a CAN or CAN FD controller to a two-wire industrial bus in compact sensor gateways, condition-monitoring hubs, and remote I/O modules. Its support for fast-phase operation up to 5 Mbit/s allows gateways to consolidate time-sensitive measurements without introducing a large transceiver footprint. The design should reserve suitable placement for the 8-HVSON exposed pad, route the differential bus as a controlled pair, and verify the transceiver's operating limits against the network's cable length and topology.

主要差異化特點
- CAN FD fast-phase operation supports higher communication bandwidth (對比TJA1042)
- Compact package preserves board area (對比TJA1044GT)
- Standby support assists system power management (對比TJA1042)
設計說明
Route CANH and CANN as a tightly coupled differential pair from the transceiver to the bus connector or isolation interface. Minimize stub branches, maintain symmetrical geometry where practical, and keep the pair away from high-current switching paths. Place the required CAN termination components at the physical ends of the bus rather than near the transceiver when the transceiver is not an endpoint.
Follow the NXP TJA1442 datasheet land pattern and reflow recommendations for the 8-HVSON package. The exposed thermal pad requires the manufacturer-specified footprint and board finish rather than a generic QFN land pattern. Inspect the solder joints after assembly and ensure the pad connection meets the recommended copper and soldering process to support electrical and thermal performance.
Provide the transceiver with the supply voltage and decoupling specified by the manufacturer, and account for the supply current drawn in normal and standby operating modes. Place input and output bypass capacitors close to their associated pins with short return paths. When the CAN node includes galvanic isolation, separate the logic-side and bus-side ground domains according to the isolation design.
Do not treat a family member or shortened ordering code as an automatic board-level substitute. Verify the complete ordering suffix, package drawing, pin names, mode-control polarity, logic thresholds, bus-bias behavior, and termination requirements. A CAN transceiver can connect to the same protocol family and still fail if its power, standby-control, or bus-node configuration differs.
合規資訊
Environmental and compliance attributes require confirmation from the exact NXP ordering code and current manufacturer product or environmental-quality information.
