Key Features
- CAN FD operation at up to 5 Mbps flexible data-rate for high-bandwidth automotive network communication
- 70 V bus-fault protection on CANH and CANL lines guarding against automotive transients and wiring faults without external TVS diodes
- Low-power sleep mode with remote wake-up capability reducing quiescent current for always-on automotive ECU designs
- AEC-Q100 Grade 1 automotive qualification in a small SON package for space-constrained ECU PCB layouts
Applications
The TCAN1051HGDRBT is designed for automotive CAN FD networks in body control modules, ADAS sensor nodes, powertrain ECUs, and gateway units where 5 Mbps data-rate and 70 V bus-fault tolerance are required. Its integrated sleep mode with remote wake-up makes it well suited for always-on vehicle networks that must minimize quiescent current during ignition-off states. The device is also used in industrial CAN FD systems where high bus-fault immunity and fast data throughput are critical requirements.

Frequently Asked Questions
What data-rate does the TCAN1051HGDRBT support and how does CAN FD compare to classic CAN in automotive networks?
The TCAN1051HGDRBT supports CAN FD at up to 5 Mbps for the data phase, compared to the 1 Mbps maximum of classic CAN 2.0. This 5x increase in data throughput allows automotive ECUs to transmit larger payloads up to 64 bytes per frame, reducing the number of frames required for ADAS sensor data and over-the-air firmware update packets on body control networks.
How does the 70 V bus-fault protection of the TCAN1051HGDRBT benefit automotive wiring harness designs?
The TCAN1051HGDRBT withstands bus voltage transients and fault conditions on CANH and CANL lines up to 70 V, protecting the internal receiver and driver circuitry from automotive load-dump events and wiring harness short-to-battery faults. This eliminates the need for separate external TVS diodes on the bus lines in many automotive applications, reducing BOM cost and PCB area while meeting ISO 7637 transient immunity requirements.
What sleep mode current does the TCAN1051HGDRBT achieve and how does remote wake-up work?
The TCAN1051HGDRBT enters a low-power sleep mode that significantly reduces quiescent current to the microampere range, enabling always-on ECU designs that must remain on the 12 V vehicle battery for months without draining it. Remote wake-up is triggered by a valid CAN bus activity pattern, automatically transitioning the transceiver from sleep to normal operating mode so the host controller can resume network communication within microseconds.
For which automotive ECU types is the TCAN1051HGDRBT most appropriate, and what certification does it carry?
The TCAN1051HGDRBT is AEC-Q100 Grade 1 automotive qualified, meaning it is tested for operation across a -40°C to 125°C junction temperature range. It is most appropriate for CAN FD gateway modules, ADAS domain controllers, powertrain ECUs, and body control modules in modern vehicles that mandate CAN FD at 5 Mbps for high-bandwidth sensor data and software-over-the-air update channels.
