TJA1057GTK/3Z - 5 Mbps High-Speed CAN Transceiver | NXP
MPN: TJA1057GTK/3Z ✓ פעילTJA1057GTK/3Z סקירה
A CAN transceiver is an interface IC that converts logic-level transmit and receive signals into the differential voltage used on a CAN network. It belongs to the broader transceiver hierarchy, which includes unidirectional and bidirectional interface devices, and ultimately connects embedded control, automotive, and industrial communication systems. The two-wire CAN bus uses CANH and CANL conductors to carry complementary differential signals between nodes.
The TJA1057GTK/3Z supports data rates up to 5 Mbps and includes normal and silent operating behavior. Its 5 V operating supply is suitable for conventional automotive and industrial electronic systems. The package uses a 0.65 mm terminal pitch in a compact 3 mm by 3 mm footprint, allowing CAN communication to be added where board area is constrained. The exposed thermal pad supports heat transfer from the transceiver into the PCB copper plane.
The device belongs to the high-speed CAN transceiver category, designed to work with a CAN protocol controller rather than directly with a microcontroller's analog inputs. Differential signaling improves common-mode rejection and allows the bus to remain reliable when multiple nodes communicate over a shared two-conductor network. Normal mode supports ordinary CAN transmission and reception, while silent mode provides a way to monitor bus activity without actively driving the bus.
Typical applications include automotive body and comfort modules, industrial automation controllers, CAN-based robotics, embedded instrumentation, and gateway equipment. The compact HVSON package is particularly useful in space-constrained controller boards where a conventional SOIC-style CAN transceiver would occupy more area. Its high-speed capability also supports communication links that exceed the rates commonly used by low-speed fault-tolerant CAN networks.
When placing the device, follow the manufacturer pin-description and package-connection guidance, provide the required supply decoupling near VCC, and connect CANH and CANL to the protected bus network. The thermal pad should connect to the appropriate ground-plane structure specified by NXP. PCB signal integrity around the CAN pins should be maintained with short return paths and controlled stub lengths.

יישומים טיפוסיים
TJA1057GTK/3Z מתאים עבור 6 יישוםs: Automotive Body Control Modules, Industrial Automation Controllers, CAN-Based Robotics, Industrial Sensor Gateways, Embedded Test and Measurement, CAN Communication Gateways.
Automotive Body Control Modules
The TJA1057GTK/3Z fits automotive body-control and comfort modules that exchange commands, sensor status, and diagnostic data over a CAN network. Its 5 Mbps maximum data rate supports high-speed CAN traffic, while the 5 V supply is compatible with conventional vehicle electronics. The 3 mm by 3 mm HVSON footprint conserves PCB area in densely populated controllers, and the package's thermal-enhanced construction helps transfer heat through the board. Design the CAN routing as a controlled differential pair, connect protection components according to the manufacturer's guidance, and confirm that the selected order code satisfies the vehicle's AEC-Q100 and environmental requirements.
מומלץ
Industrial Automation Controllers
The TJA1057GTK/3Z is suitable for PLC modules, factory controllers, and remote I/O nodes that connect embedded logic to a two-wire CAN field bus. Its 5 Mbps capability supports high-speed communication between machine controllers, sensors, and actuators, while normal and silent operation gives the node useful control over bus participation. The compact 8-terminal HVSON package allows placement near the board edge and connector without consuming the larger area of many leaded transceivers. Keep CANH and CANL routing symmetrical, provide the required local supply bypassing, and apply surge protection appropriate to the industrial cable environment.
מומלץ
CAN-Based Robotics
The TJA1057GTK/3Z can connect a robot controller to motors, sensor modules, safety controllers, and remote manipulators over CAN. A 5 Mbps CAN interface supports responsive command and status traffic, and the 3 mm by 3 mm package suits compact embedded robotics electronics. Silent mode can help a node monitor activity without asserting normal transmit behavior, depending on the connected controller implementation. Because robotic systems may combine motor switching, long cables, and electrically noisy machinery, keep the differential bus away from switching nodes and use protection and grounding strategies consistent with the cable length and installation environment.
מומלץ
Industrial Sensor Gateways
The TJA1057GTK/3Z is appropriate for gateways that aggregate measurements from remote sensors and publish them through a CAN backbone. Its high-speed CAN capability allows a gateway to support multiple traffic classes while maintaining a compact transceiver footprint. The 5 V supply and 8-terminal package simplify integration into small sensor-interface boards, and normal or silent operating behavior supports both active networking and diagnostic monitoring. Preserve a continuous ground reference along the bus, minimize stubs, and verify the controller's bit timing and termination arrangement across the complete network rather than only at the gateway.
מומלץ
Embedded Test and Measurement
The TJA1057GTK/3Z can provide the physical-layer connection for compact test instruments, diagnostic adapters, and service tools that communicate with CAN-equipped equipment. The 5 Mbps bus rate supports rapid data transfer and the small HVSON package leaves more board area for measurement circuitry or connectors. Silent operation may be useful when a tester needs to listen to traffic without introducing normal-mode bus activity. For laboratory and service equipment, use short, well-terminated test leads, observe common-mode limits, and add suitable transient protection when connecting the interface to external harnesses.
מומלץ
CAN Communication Gateways
The TJA1057GTK/3Z fits gateway modules that translate between a CAN physical bus and another embedded communication interface. Its 5 Mbps capability provides sufficient bandwidth for status, configuration, and diagnostic traffic, while the compact 3 mm by 3 mm package simplifies multi-interface board layouts. The CAN side should be implemented as a controlled differential pair with correct termination at the physical ends of the bus. Grounding and isolation decisions depend on the potential difference between gateway and connected equipment, so verify common-mode voltage, surge exposure, and shielding before deploying the gateway outside a controlled enclosure.

הערות תכנון
Route CANH and CANL as a tightly coupled differential pair with continuous reference-plane support, matched trace geometry, and minimal stubs. Keep the transceiver, termination, protection components, and connector interface in the same signal region to avoid discontinuities. Position the 120-ohm bus termination at the physical ends of the network rather than at every node, and review the complete bus topology before relying on a nominal data rate of 5 Mbps.
Place the required VCC and VIO bypass capacitors immediately beside their associated device pins, with the shortest possible ground-return path. Decouple the transceiver locally instead of relying on supply traces shared with motors, relays, or other high-current loads. Verify startup, mode-control timing, and supply tolerances against the manufacturer data sheet, especially when the CAN controller can begin transmitting before the transceiver's supply is fully stable.
Use the exposed thermal structure of the HVSON package as an intentional heat-spreading connection to PCB copper. Keep high-current or high-temperature copper regions away from the transceiver unless thermal coupling is intentional. Review ambient temperature, enclosure temperature, and the device's operating-temperature grade for the selected suffix. The compact package can conduct heat efficiently into the board, but thermal performance still depends on copper area, layer count, and neighboring heat sources.
Do not treat a similar TJA1057 ordering code as interchangeable solely because the package matches. Confirm temperature grade, AEC-Q100 status, packing, pin configuration, and mode-control behavior against the manufacturer ordering information. Avoid connecting CANH or CANL to logic-level outputs, and ensure that bus protection does not distort the differential signal or exceed the transceiver's common-mode and transient limits.
