TJA1057GTK Descripción general
A CAN transceiver is a physical-layer interface IC that converts the digital transmit (TXD) and receive (RXD) signals from a CAN controller into the differential CANH and CANL bus voltages defined by the ISO 11898-2 standard. Within the broader hierarchy, a CAN transceiver sits below the CAN controller (typically inside a microcontroller) in the Open Systems Interconnection (OSI) model and sits above the physical bus medium. Without a transceiver, a controller cannot meet the bus-level timing, drive strength, or fault protection that an automotive CAN bus demands.
Key features include a low-current standby mode with remote wake-up via bus activity, thermal protection, bus-dominant time-out to prevent a stuck node from blocking the bus, and an undervoltage detection on the VCC supply. The HVSON-8 package features an exposed thermal pad that reduces junction-to-ambient thermal resistance, enabling AEC-Q100-qualified automotive operation across the -40C to +125C range. The TJA1057 is pin-compatible with the legacy TJA1050 footprint in SO-8 but uses the smaller, thermally enhanced HVSON-8 package in this GTK suffix variant.
The transceiver uses a symmetric differential driver stage that minimizes electromagnetic emissions, and the receiver incorporates a wide common-mode range to tolerate ground shifts between nodes on long bus runs. An integrated slope-control resistor optimizes the rise/fall times of the CANH/CANL edges to balance emissions against bit-timing symmetry.
Typical applications include automotive body control modules, gateway ECUs, infotainment CAN interfaces, industrial CANopen networks, and any 12V/24V automotive subsystem that communicates via CAN at speeds from 10 kbit/s to 1 Mbit/s. Designers select the TJA1057GTK when EMC performance and a small PCB footprint outweigh the need for the higher bus-fault voltage ratings of the TJA1055 or TJA1044.
When designing with this part, place a 100 nF decoupling capacitor as close as possible to the VCC pin, keep the CANH/CANL traces short and symmetric with characteristic impedance near 120 ohm, and verify that the termination resistance at each end of the bus totals 120 ohm to prevent signal reflections.

Aplicaciones típicas
TJA1057GTK es adecuado para 6 aplicacións: Automotive Body Control Module (BCM), In-Vehicle Network Gateway ECU, Industrial CANopen Motor Drive, Automotive Infotainment CAN Interface, Battery Management System (BMS) CAN Bus, Tractor and Off-Highway Vehicle CAN Network.
Automotive Body Control Module (BCM)
The TJA1057GTK's 4.75V-5.25V supply, 1 Mbit/s data rate, and AEC-Q100 qualification make it a strong fit for body control modules that aggregate door, lighting, and wiper signals across a high-speed CAN backbone. The HVSON-8 (3x3 mm) package with exposed thermal pad dissipates heat effectively in the sealed BCM enclosure where ambient temperatures can reach 85 C inside the cabin. The integrated bus-dominant time-out protects the bus if the BCM firmware hangs and leaves the TXD dominant indefinitely. A typical circuit places the transceiver between a 5V regulator and an automotive MCU (e.g. S32K1xx) with a 100 nF decoupling capacitor on VCC and a split 120 ohm termination at the bus connector.

In-Vehicle Network Gateway ECU
Gateway ECUs bridge CAN, CAN FD, LIN, and Ethernet domains in modern vehicles, and the TJA1057GTK provides the high-speed CAN physical interface on each isolated network segment. Its low standby current and remote wake-up capability support the GW's partial-network listening mode so that the rest of the vehicle network can shut down without losing connectivity. The 1 Mbit/s ceiling accommodates classical CAN traffic from powertrain and chassis segments; designers pairing it with an FD-tolerant controller can still run the bus at classical rates. The exposed thermal pad keeps the junction temperature below 150 C even when the GW is densely populated with multiple transceivers on the same PCB.
Recomendado
Industrial CANopen Motor Drive
Industrial servo drives and inverters use CANopen over high-speed CAN for distributed motion control, and the TJA1057GTK's wide common-mode range tolerates ground potential differences across long motor cables. The transceiver is rated for continuous operation at 1 Mbit/s with controlled edge symmetry, satisfying the strict CANopen DS301 bit-timing requirements over cables up to ~30 m. The HVSON-8 (3x3 mm) footprint is small enough to fit on the densely packed control board of a compact servo drive. Compared to a discrete CAN driver, the integrated thermal shutdown and undervoltage lockout reduce PCB area and improve robustness against 24V industrial bus faults when used with appropriate external protection.
Recomendado
Automotive Infotainment CAN Interface
Head units and instrument clusters interface with the vehicle CAN bus for body and chassis data, and the TJA1057GTK delivers clean differential signalling that minimizes radiated emissions into the audio and RF sections of the infotainment stack. The optimizer-designed slope control inside the driver keeps CANH/CANL edges within OEM EMC limits without external series resistors. The standby mode with bus wake-up allows the infotainment system to enter low-power state while still responding to remote wake frames from door-unlock events. Selecting the HVSON-8 (3x3 mm) package keeps the CAN interface footprint under 10 mm squared on the main processor board.
Recomendado
Battery Management System (BMS) CAN Bus
Battery management systems use high-speed CAN to report per-cell voltage, temperature, and state-of-charge telemetry to the vehicle's energy management ECU. The TJA1057GTK's wide -40 C to +125 C operating range covers the harsh thermal environment inside a battery pack, and its integrated bus-fault tolerance protects the transceiver during load-dump transients on the 12V rail. The exposed thermal pad supports the high ambient temperatures that occur adjacent to battery cells during fast charging. The receiver's wide common-mode range rejects ground shifts between the BMS board and the chassis, preventing false error frames during heavy inverter switching noise.
Recomendado
Tractor and Off-Highway Vehicle CAN Network
Agricultural tractors, construction equipment, and off-highway vehicles use SAE J1939 over high-speed CAN for engine, transmission, and implement communication, and the TJA1057GTK supports the required 250 kbit/s and 500 kbit/s J1939 bit rates with tight bit-timing symmetry. The transceiver's superior ESD and EMC performance is essential to survive the harsh electrical environment of 24V heavy-vehicle systems with load-dump and jump-start surges. The HVSON-8 package withstands the high vibration levels in off-highway machinery when the PCB is properly fastened and the exposed pad is soldered to a continuous ground plane.

Notas de diseño
Place a 100 nF X7R ceramic decoupling capacitor within 2 mm of the VCC pin and connect the exposed thermal pad (e-pad) to a continuous ground plane with at least four thermal vias. The HVSON-8 e-pad is the primary heat-dissipation path and must be soldered to deliver the rated thermal performance. Keep the CANH and CANL traces as short as possible and route them as a 120 ohm differential pair without stubs to minimize reflections at 1 Mbit/s.
Route the CANH/CANL pair with matched length (delta < 2 mm) and a differential impedance near 120 ohm, matching the cable impedance. Use a split termination (two 60 ohm resistors in series with a 4.7 nF to 100 nF capacitor to ground at the centre node) instead of a single 120 ohm resistor at each bus end; this improves EMC immunity by AC-coupling common-mode noise to ground. Keep digital signals (TXD, RXD, STB) routed away from the CAN traces to avoid coupling noise into the bus.
Do not drive the TJA1057GTK from a 3.3V MCU without a level shifter - the VCC supply must be between 4.75 V and 5.25 V; logic signals at 3.3V may fall outside the TXD/RXD threshold. Avoid placing 120 ohm termination inside the transceiver footprint; place it directly across the CANH/CANL pins at the bus connector to avoid stub-induced reflections. Finally, never connect STB to a slow RC network - if standby control is not used, tie STB to GND to ensure the part remains in normal mode.
