TJA1441BT/0Z - 5 Mbps CAN FD Transceiver | NXP | SOIC-8
料号： TJA1441BT/0Z ✓ 量产中TJA1441BT/0Z 概述
A CAN transceiver is an interface IC that converts logic-level transmit and receive signals into a differential CAN bus and presents the bus state to a controller. The TJA1441 family belongs to the broader CAN interface, transceiver, and industrial communication hierarchy. Its 5 V operation, 5 Mbit/s data-rate capability, 3 mA quiescent current, and normal or Silent operating modes make it appropriate for distributed embedded systems that need reliable communication over a two-wire differential bus.
The TJA1441BT/0Z includes ESD protection, undervoltage protection, thermal shutdown protection, and a TXD dominant timeout function. These protections support robust operation in automotive, industrial, and embedded CAN networks where cable transients and supply disturbances are common. The 150°C maximum operating temperature shown in the product listing supports use across demanding temperature ranges, while AEC-Q100 qualification is identified in the product description for automotive-oriented designs.
Typical uses include automotive body electronics, industrial automation equipment, robotics controllers, building automation gateways, and CAN-connected sensors. The 8-pin SOIC-8 package is straightforward to assemble on conventional PCB technology and can replace compatible existing CAN transceivers without changing the controller or bus software. For a new design, confirm the exact pin description, recommended external components, bus termination, and transceiver mode timing in the NXP TJA1441 datasheet.
The most important design trade-off is that this is a CAN physical-layer transceiver, not a standalone CAN controller. The host MCU or other protocol controller must generate TXD and receive RXD, while the PCB must provide correct CANH and CANL routing, termination at appropriate bus locations, adequate grounding, and protection for the application environment. The component should not be selected solely by its listed data rate; verify supply voltage, I/O voltage compatibility, mode-control logic, and bus fault requirements against the complete device specification.

典型应用
TJA1441BT/0Z 适用于 6 应用s: Automotive Body Control Networks, Industrial Automation Equipment, CAN-Connected Sensor Networks, Robotics and Motion Control, Building Automation Gateways, CAN Protocol Testing and Diagnostics.
Automotive Body Control Networks
The TJA1441BT/0Z fits automotive body and comfort modules that exchange control data over a two-wire CAN network. Its up-to-5 Mbit/s CAN FD capability supports newer high-bandwidth bus segments, while the listed -40°C to +150°C operating range and AEC-Q100 identification support harsh-temperature qualification workflows. The 8-pin SOIC-8 package also simplifies reuse of an existing transceiver footprint. Place the transceiver beside the CAN connector and controller, route CANH and CANL as a controlled differential pair, and verify the selected order code against the vehicle's electrical and qualification requirements.
推荐
Industrial Automation Equipment
Use the TJA1441BT/0Z as the physical-layer interface between an industrial controller and a distributed CAN bus containing drives, sensors, or remote I/O. The 5 Mbit/s capability can improve update bandwidth when the full network is designed for CAN FD, and Silent mode provides a defined alternative operating state for controlled bus management. Its 4.5 V to 5.5 V supply range and 3 mA quiescent current suit compact embedded modules. Confirm protocol-controller timing, termination placement, fault behavior, and isolation requirements before using the transceiver in safety-related or electrically noisy machinery.
推荐
CAN-Connected Sensor Networks
The TJA1441BT/0Z is appropriate for environmental, pressure, temperature, and energy-monitoring nodes that report measurements through a shared CAN bus. CAN FD data-rate support can reduce the time required for larger payloads, provided every node and the physical network are configured for the selected rate. The low 3 mA quiescent current helps conserve power in duty-cycled endpoints, and the small SOIC-8 package supports compact sensor interfaces. Designers should verify the logic levels presented by the controller, use bus termination only at designated network locations, and validate the entire network topology for bit timing and fault recovery.
推荐
Robotics and Motion Control
The TJA1441BT/0Z can connect a robot controller, motor controller, sensor concentrator, or safety-monitoring module to a robust CAN communications backbone. Supporting up to 5 Mbit/s is valuable when the system carries commands, position feedback, diagnostics, and status updates across multiple nodes. Normal and Silent operating modes allow controlled behavior during configuration or fault-management states, subject to the exact timing definitions in the manufacturer datasheet. For motor drives, keep the transceiver and bus routing separated from switching nodes, follow recommended return-path and grounding practices, and validate transient immunity at the connector and cable interface.
推荐
Building Automation Gateways
The TJA1441BT/0Z is suitable for building-automation gateways that bridge controllers to lighting, HVAC, access-control, or energy-management devices using CAN. The 5 Mbit/s capability supports CAN FD traffic where concentrated diagnostics or configuration data would otherwise increase bus utilization. Its 3 mA quiescent current is useful in continuously powered gateways, while Silent mode can support predictable bus states in managed network segments. Select the proper termination strategy for each bus section and confirm that the building controller supports the same CAN FD bit timing and protocol features. The manufacturer's documentation should govern connector protection, grounding, and supply decoupling.
推荐
CAN Protocol Testing and Diagnostics
The TJA1441BT/0Z can be used in communication analyzers, interface adapters, and diagnostic fixtures that need access to a physical CAN bus while remaining close to the controller electronics. Its 5 Mbit/s CAN FD support covers high-speed bus segments, and the Normal and Silent modes assist controlled connection and disconnection during test sequences. The 8-pin SOIC-8 format supports compact probe hardware and established PCB patterns. Confirm the electrical limits of the analyzer inputs, use suitable bus protection where cables are exposed, and review timeout and bus-fault specifications to ensure the test sequence cannot accidentally disturb the network under examination.

设计说明
Place the TJA1441BT/0Z close to the CAN connector and connect CANH and CANL as a controlled differential pair. Keep the CAN traces away from switching-power nodes, high-speed clock edges, and unrelated high-current return paths. Provide the recommended supply decoupling directly at the transceiver pins and follow the manufacturer layout guidance for the ground connection. A short, symmetrical bus escape reduces the chance that cable transients or board-level coupling distort the differential signal.
Do not assume that a shared 8-pin footprint guarantees that every CAN transceiver has identical mode-control or timing behavior. Before replacing TJA1051, TJA1057, or another TJA144x member, compare TXD and RXD behavior, bus-stuck handling, timeout functions, Silent-mode logic, I/O voltage, and startup sequencing. Review the NXP pin-description table and timing diagrams for the exact ordering code, especially when firmware already relies on a defined mode-control sequence.
Apply CAN termination only at the physical endpoints of the bus, using the resistor value specified by the selected system design and the NXP application guidance. Do not terminate every node in a multidrop network because excessive parallel resistance can impair recessive-bit behavior. Route the return path beneath the pair where the recommended layout permits, maintain consistent spacing, and test both normal communication and recovery from bus short, open, and dominant-fault conditions.
Protect external cable interfaces with a network designed for the actual ESD and surge environment. Keep protection components close to the connector and provide a defined return path for transient current into the board ground or chassis structure. Verify that the protection network does not add excessive capacitance that reduces signal margin at the operating bit rate. The on-chip ESD protection does not remove the need for an application-level bus protection strategy.
Use a stable 5 V supply within the 4.5 V to 5.5 V operating range and check the controller I/O voltage independently from the transceiver supply. Place the input bypass capacitor at the appropriate power pin and verify supply sequencing against the host controller. The 3 mA quiescent current is a useful low-power figure, but the complete system budget must also include controller, bus, and protection-network current under Normal and Silent operating states.
