Typical Applications
TCAN1051HVDQ1 is suitable for 6 applications: Body Control Module (BCM), Gateway Module, Battery Management System (BMS), Advanced Driver Assistance Systems (ADAS), Powertrain Control, On-Board Diagnostics (OBD-II).
Body Control Module (BCM)
The TCAN1051HVDQ1 is ideal for body control modules where robust communication between door locks, lighting, and window controls is critical. Its ±58 V fault protection guards against shorts to 12V/24V battery, common in automotive wiring harnesses. The 2 Mbps CAN FD data rate ensures fast message transfer for real-time control. With AEC-Q100 qualification and -55°C to +125°C operation, it meets reliability requirements. The silent mode allows the BCM to monitor the bus during diagnostics without transmitting.
Recommended
Gateway Module
In automotive gateway modules, multiple CAN FD buses are bridged to route messages between domains. The TCAN1051HVDQ1 supports 2 Mbps CAN FD, allowing high-bandwidth data transfer between the powertrain, chassis, and infotainment domains. Its wide common-mode range and low EMC emissions enable reliable operation with twisted-pair wiring. The fault protection prevents a bus short from taking down the entire gateway. The device's small SOIC-8 package allows dense placement on gateway PCBs.
Recommended
Battery Management System (BMS)
For battery management systems, the TCAN1051HVDQ1 provides reliable communication between the battery monitoring ICs and the main control unit. The ±58 V fault protection protects against transients and shorts to battery terminals, crucial in electric vehicle packs. Its CAN FD support at 2 Mbps enables streaming of cell voltage and temperature data. The device operates over the full automotive temperature range, from -55°C to +125°C, ensuring reliable performance in exposed battery compartments. The low quiescent current helps minimize power drain when the vehicle is parked.
Recommended
Advanced Driver Assistance Systems (ADAS)
In ADAS, the TCAN1051HVDQ1 is used to transmit sensor data from radar and cameras to the central processor at 2 Mbps CAN FD rates. Its robust fault protection ensures the bus survives shorts in harsh environments, while the wide common-mode range maintains data integrity under ground shifts. The device's ISO 11898-2 compliance ensures interoperability with other ECUs. Its small footprint (8-SOIC) and AEC-Q100 qualification make it suitable for space-constrained sensor modules. The silent mode supports diagnostic and network management protocols.
Recommended
Powertrain Control
The TCAN1051HVDQ1 is well-suited for powertrain control units, where the CAN bus connects the engine, transmission, and hybrid systems. It supports high-speed CAN FD for real-time control and diagnostics, up to 2 Mbps. The ±58 V fault protection guards against inductive transients and short circuits to 12V/24V rails. Operating from -55°C to +125°C, it can survive engine compartment temperatures. Its low supply current (45 mA) keeps power dissipation minimal, and the 8-SOIC package is compatible with existing ECU layouts.
Recommended
On-Board Diagnostics (OBD-II)
The TCAN1051HVDQ1 is essential for OBD-II diagnostics interfaces, allowing external tools to query the vehicle's ECUs. It supports high-speed CAN FD at 2 Mbps, exceeding the 500 kbps classic CAN speed, enabling faster diagnostics. The device's silent mode allows the test tool to listen to the bus without interfering. The fault protection prevents damage from misconnected probes, and the wide operating temperature range ensures function under all weather conditions. Its pin-compatible SOIC-8 package simplifies replacement.

- CAN FD support up to 2 Mbps (vs SN65HVD230)
Design Notes
The SOIC-8 package has limited thermal dissipation. At 5.5V supply and 45mA current, power dissipation is low (~0.25W), typically no heatsink is needed. However, in high-noise environments with bus shorts, keep the junction temperature below 150°C. Use a copper pour under the device to improve thermal conductivity and ensure adequate vias to the ground plane.
Place a 100nF decoupling capacitor as close to VCC as possible, and add a 10µF bulk capacitor near the device. Route CANH and CANL as a balanced differential pair with 120Ω termination at the far end. For improved EMC, use a split termination network with a center-tapped capacitor to ground. Keep the trace lengths balanced and away from high-speed digital lines.
Do not exceed the 5.5V supply voltage. Connect the S pin to an I/O to control silent mode; leaving it floating may cause undefined operation. Ensure bus voltage does not exceed ±58V; otherwise, the device may be damaged. Always verify the pinout before substituting with other brands, as some SOIC-8 CAN transceivers have different pin assignments.
