TJA1057GT/1Z Descripción general
What is a CAN transceiver? A CAN transceiver is a physical-layer interface IC that converts digital transmit/receive logic signals from a microcontroller CAN controller into differential voltage signals on a two-wire CAN bus (CANH and CANL). It belongs to the hierarchy: CAN transceiver -> CAN interface IC -> Interface ICs -> Integrated Circuits. The transceiver also provides bus protection, fault tolerance (dominant/recessive clamping, TXD dominant time-out), and EMC/ESD robustness required in automotive environments.
Key features of the TJA1057 include very low current consumption in standby and go-to-sleep modes with remote wake-up capability, an integrated VIO supply pin on /3 variants for direct interfacing with 3.3V and 5V microcontrollers, and an undervoltage detection on VCC and VIO supplies. The TJA1057 implements the CAN physical layer per ISO 11898-2:2016 and SAE J2284-1 to SAE J2284-5, with the TJA1057T explicitly specified for data rates up to 1 Mbit/s.
Architecturally, the device uses a differential transmit/receive path with slope control for low-EMI operation, an internal LDO for digital supply, and a sophisticated thermal protection scheme. Its split-pin output stage balances common-mode stability with low electromagnetic emissions, making it well-suited for automotive body, chassis, and powertrain networks.
Typical applications include automotive body control modules, gateway ECUs, infotainment CAN nodes, industrial CAN automation nodes, and CAN-FD enabled instrument clusters. Its robustness against ESD (>6 kV HBM) and bus fault voltages (±58 V) makes it dependable in harsh electrical environments.
When designing with this device, ensure proper bus termination with 120 ohm resistors at each end of the bus and a common-mode choke for EMI-sensitive applications. The TJA1057 requires careful placement of the VCC decoupling capacitor close to pin 1 to maintain supply stability during dominant-to-recessive transitions.

Aplicaciones típicas
TJA1057GT/1Z es adecuado para 6 aplicacións: Automotive Body Control Module (BCM), CAN Gateway ECU and Network Bridging, Industrial CAN Automation Nodes, Infotainment CAN Interface, Electric Vehicle Charging Communication (ISO 15118 subordinate link), Agricultural and Off-Highway Vehicle CAN.
Automotive Body Control Module (BCM)
The TJA1057GT/1Z is well-suited for automotive body control modules where reliable CAN communication is required across window, door, lighting, and HVAC subsystems. The ISO 11898-2:2016 compliance and -40 C to +125 C operating range match automotive under-hood and cabin temperature extremes. With typical standby current in the low-microamp range, the part minimizes parasitic battery drain when the BCM is in sleep mode. Placed between the 5V MCU and the CAN bus, the transceiver converts MCU digital TXD/RXD into CANH/CANL differential signals, while the integrated bus-fault protection defends against shorts to battery or ground. Replacing legacy TJA1050 with TJA1057GT improves EMC margins and reduces quiescent consumption, which is critical for always-on body networks.

CAN Gateway ECU and Network Bridging
The TJA1057GT/1Z serves as the physical interface in CAN gateway ECUs bridging body and powertrain CAN buses at different speeds. Its CAN FD support (on GT variants) enables tunneling of larger CAN FD payloads between sub-networks without stack-level fragmentation. The wide common-mode range and bus-fault tolerance (±58 V on the bus pins) ensure reliability when one side of the gateway is connected to a noisy powertrain segment. With 1 Mbit/s classic CAN support on the T variant, it can also operate in mixed-speed bridge architectures. Designers typically place two TJA1057GT/1Z devices per gateway channel, with common-mode chokes on CANH/CANL for EMI suppression and 120 ohm termination at each end of the internal gateway backbone.
Recomendado
Industrial CAN Automation Nodes
Industrial CANopen and DeviceNet nodes benefit from the TJA1057GT/1Z's robust fault handling and wide temperature tolerance, even though it is spec'd primarily for automotive. The ISO 11898-2:2016 compliance ensures inter-operability with industrial CANopen stacks and the CANopen DS301/DS401 device profile layer. The low standby current enables field devices to comply with energy-saving mode requirements when not actively scanning the bus. Placement typically pairs the transceiver with an industrial MCU (e.g., STM32F4 series) handling CANopen protocol stack execution. The TJA1057GT/1Z provides galvanic fault tolerance at the bus pins which is valuable in motor drive cabinets where switching transients often couple to communication wiring.
Recomendado
Infotainment CAN Interface
Infotainment head units connect to the vehicle CAN backbone to read body, climate, and diagnostic data, and the TJA1057GT/1Z provides the physical-layer interface for these communications. Its low loop delay (typically <250 ns) ensures deterministic bus timing required for audio system synchronization and cluster-to-head-unit data exchange. The integrated thermal shutdown protects against fault conditions caused by shorted wiring harnesses common in dash-mounted electronics. Designers wire the transceiver's RXD output to a CAN-capable MCU or SoC running the infotainment OS, with the TXD driven by software. The split-pin (SPLIT) output feature on some variants provides stable common-mode biasing beneficial for long harness runs typical in vehicles.
Recomendado
Electric Vehicle Charging Communication (ISO 15118 subordinate link)
While ISO 15118 High-Level Communication for EV charging primarily uses PLC, supplemental CAN links to the EVCC and SECC benefit from the TJA1057GT/1Z's robust bus handling and VIO flexibility for direct 3.3 V MCU interface. The /3 variants' VIO pin eliminates level shifters when paired with low-voltage MCUs, reducing BOM count and improving reliability in space-constrained charging assemblies. The wide bus-fault tolerance defends against ground loops and transient voltages present in EV charging station environments. Implementation pairs the transceiver with a 3.3V MCU running the charging controller firmware, with termination and common-mode choke components selected to meet automotive EMC requirements.
Recomendado
Agricultural and Off-Highway Vehicle CAN
Off-highway vehicles such as tractors, harvesters, and construction equipment use SAE J1939 (based on CAN) for engine and implement communication, and the TJA1057GT/1Z's robust design handles these demanding environments. ISO 11898-2:2016 compliance interoperates with J1939-11 and J1939-14 physical layers, while the wide operating temperature and bus-fault tolerance survive engine bay heat and load-dump transients. Designers typically use a CAN gateway to bridge J1939 engine data with NMEA 2000 marine or ISOBUS agricultural bus standards. The 5V VCC single-supply simplifies integration into existing 12V/24V vehicle electrical systems with standard LM7805 or switching regulator rails.

Notas de diseño
Place the VCC decoupling capacitor (typically 100 nF ceramic) within 2 mm of pin 3 (VCC), with a short, wide ground return to pin 2 (GND). For SOIC-8 CAN transceivers, the ground plane stitching beneath the device must remain intact to maintain thermal dissipation and reduce radiated EMI. Estimated: with proper 4-layer layout (top signal, GND plane on layer 2), the ground inductance is below 1 nH - critical for stable operation during dominant-to-recessive transitions when bus current changes of tens of mA occur within nanoseconds.
Route the CANH and CANL traces as a tightly coupled differential pair with 100 ohm characteristic impedance and constant 5 mil spacing, per IEC 62228-3 EMC layout guidelines. Match trace lengths within 1 mm to avoid common-mode skew. Add a split termination network (typically 60 ohm in series, 60 ohm in parallel with 4.7 nF to ground) at each end of the bus for high-speed CAN signaling. Per NXP TJA1057 application note, common-mode choke (e.g., 100 uH) in series with CANH/CANL suppresses emissions above 30 MHz.
Do not leave pin 5 (STB) floating on the TJA1057GT/1Z - it must be tied to VCC through a 10 kohm pull-up for normal operation, or driven by MCU GPIO for standby mode control. Pin 8 (NC) on some variants exposes SPLIT; if your design uses an external common-mode stabilization circuit, verify pin 8 function from the datasheet revision before connecting. Estimated: ignoring standby mode wiring is the most common cause of 'stuck in standby' failures where the transceiver appears dead despite correct VCC and CANH/CANL signals.
While CAN transceivers dissipate modest power, the SOIC-8 package has thermal resistance (theta_JA) of approximately 120-150 C/W on a standard 4-layer JEDEC test PCB. With bus fault current up to 250 mA per bus pin in worst case, internal dissipation can reach ~250 mW during sustained fault, resulting in a 30-40 C junction temperature rise above ambient. Per datasheet, the integrated thermal shutdown typically engages at 165-175 C junction, providing protection under short-circuit conditions.
