TCAN1051HVDQ1 - ±58V CAN FD Transceiver 2Mbps | TI
MPN: TCAN1051HVDQ1 ✓ NakahandaTCAN1051HVDQ1 Ulas
A CAN transceiver is the physical layer interface between a CAN protocol controller and the differential bus lines CANH and CANL. It converts controller logic signals to differential bus signals and back, forming the lowest layer of a Controller Area Network below the MCU. The TCAN1051HVDQ1 is a high-speed CAN FD transceiver qualified to AEC-Q100 and compliant with ISO 11898-2:2016.
Key features include fault protection up to plus or minus 58 V on CANH and CANL, a silent mode for diagnostics (listen-only), and a dominant timeout (TXD time-out) that prevents a controller fault from locking up the bus. The device draws a typical 45 mA operating supply current, and its wide common-mode range of -12 V to +12 V plus split termination capability enhance EMC performance in electrically noisy vehicles.
Architecturally, the transceiver uses bipolar differential driver/receiver technology with integrated thermal shutdown protection, making it robust in engine compartments, battery packs, and other high-temperature automotive locations. It is pin-compatible with standard high-speed CAN transceivers, enabling drop-in upgrades to CAN FD and to higher fault tolerance in existing designs.
Typical applications include body control modules, gateway modules, battery management systems, and ADAS ECUs, where wide bus fault tolerance and full automotive temperature range ensure reliable inter-module communication even with wiring faults present.
Design tip: terminate the bus with 120 ohm at both ends, keep the transceiver close to the CAN controller, use the silent mode pin for network management during diagnostics, and provide solid decoupling and a robust ground plane for EMC. Pricing per unit is approximately as of 2026-08-30 per distributor listings.

Tipikal na mga Gamit
TCAN1051HVDQ1 ay nararapat para sa 6 aplikasyons: Body Control Module (BCM), Battery Management System (BMS), Automotive Gateway Module, ADAS ECU, Industrial CAN / CANopen Networks, Electric Powertrain and OBC Communication.
Body Control Module (BCM)
In a body control module, the TCAN1051HVDQ1 bridges the MCU CAN controller to the vehicle CAN bus handling lighting, door, and access functions. Its ±58 V fault protection survives wiring-harness shorts to battery or load-dump events common in door and lamp circuits, while the -55C to +125C range covers engine-bay-mounted BCMs. Silent mode lets the module listen during diagnostics without disturbing bus traffic. Per ISO 11898-2:2016, the transceiver drives 2 Mbps CAN FD frames reliably with split termination for EMC.
Inirekomenda
Battery Management System (BMS)
Battery management systems in EVs place CAN transceivers near high-voltage contactors and switch loads, where transient faults are frequent. The TCAN1051HVDQ1 withstands ±58 V faults on CANH/CANL and integrates thermal shutdown, making it well suited to BMS communication between cell-monitoring MCUs and the vehicle gateway. Operating from a 4.5 V to 5.5 V rail at 45 mA typical, it supports 2 Mbps CAN FD traffic for cell-voltage and temperature telemetry, and the dominant timeout prevents a latched controller from blocking fault broadcasts.
Inirekomenda
Automotive Gateway Module
Gateway modules aggregate multiple CAN, CAN FD, and Ethernet domains, so transceiver fault robustness directly affects vehicle availability. The TCAN1051HVDQ1 tolerates ±58 V bus faults and -12 V to +12 V common-mode voltage, keeping a gateway node alive during harness faults while other nodes recover. Its 2 Mbps CAN FD rate matches modern gateways, and AEC-Q100 qualification plus the SOIC-8 footprint permit dense multi-channel layouts with split termination filtering on each port for EMC.
Inirekomenda
ADAS ECU
ADAS ECUs exchange sensor and actuator data over low-latency CAN FD links where frame integrity is safety-critical. The TCAN1051HVDQ1 provides deterministic 2 Mbps CAN FD signaling compliant with ISO 11898-2:2016, ±58 V fault tolerance against power-domain faults from radar/camera actuators, and -55C to +125C operation for windshield- or radiator-adjacent mounting. Silent mode supports diagnostic sniffing of the ADAS bus during calibration without injecting traffic, and thermal shutdown protects the module in hot engine-bay enclosures.
Inirekomenda
Industrial CAN / CANopen Networks
In factory automation, CANopen and DeviceNet-style nodes benefit from the TCAN1051HVDQ1 although it is automotive-qualified; the AEC-Q100 margin exceeds industrial requirements. The transceiver tolerates ±58 V bus faults caused by miswired 24 V or 48 V lines, works from a standard 5 V supply at 45 mA, and drives 2 Mbps CAN FD segments up to 40 m. Split termination and -12 V to +12 V common-mode range suppress motor-drive noise, and its SOIC-8 footprint drops into legacy 82C251-style layouts after pin check.
Inirekomenda
Electric Powertrain and OBC Communication
Onboard chargers and traction-inverter controllers sit in high-EMI, high-temperature zones where CAN links must survive transient coupling. The TCAN1051HVDQ1s ±58 V fault tolerance, thermal shutdown, and -55C to +125C rating keep the charger-to-VCU CAN FD link alive during load dump and ignition transients. Operating from 4.5 V to 5.5 V with 45 mA typical draw, it transmits 2 Mbps frames per ISO 11898-2:2016, and the TXD dominant timeout stops a hung controller from broadcasting dominant state onto the shared powertrain bus.

Talaan ng Disenyo
Place the TCAN1051HVDQ1 as close as possible to the CAN connector and the MCU CAN controller. Decouple VCC with 0.1 uF plus 4.7 uF ceramic capacitors within 2 mm of pin 3. Route CANH/CANL as a matched differential pair; keep TXD/RXD traces short to preserve 2 Mbps timing margins.
Terminate the bus with 120 ohm at both physical ends only - stub termination causes reflections that corrupt CAN FD data-phase bits. If silent mode is unused, tie the mode pin to its inactive level rather than leaving it floating. Do not rely on the transceiver to survive sustained battery shorts indefinitely; the ±58 V rating covers transients and faults, but verify fuse coordination in the harness.
Use split termination (two 60 ohm resistors with a 4.7 nF to 10 nF center capacitor to ground) to filter common-mode noise in electrically noisy vehicles. A common-mode choke between transceiver and connector further suppresses RF emissions per vehicle EMC requirements. Keep the ground plane unbroken under the bus lines.
The transceiver dissipates power mainly during dominant-state bus driving. At 45 mA typical supply current and a 45 ohm effective bus load, dissipation stays well within SOIC-8 limits, but verify junction temperature at +125C ambient with worst-case bus load and sustained dominant traffic; enable thermal shutdown margin by minimizing nearby hot components.
