Product details

Automotive CAN bus transceiver with 2 Mbps throughput

The receiver hysteresis of 120 mV provides noise immunity on the bus, reducing false bit detection in electrically noisy environments like motor drives or ignition systems.

Supply range and bus voltage tolerance

The single driver and single receiver pair handles standard CAN 2.0 and CAN FD frames at the full 2 Mbps rate. The 120 mV receiver hysteresis filters bus ringing and common-mode noise, which is critical when the twisted-pair cable runs through the engine bay or past high-current switching loads.

For a production BOM that requires AEC-Q100-qualified CAN transceivers, this part avoids the last-time-buy planning that obsolete or NRND parts force.

Frequently asked questions

Is TCAN1051HVDRQ1 suitable for automotive 5V CAN bus systems?

Yes.

What is the difference between TCAN1051HVDRQ1 and TCAN1051GVDRQ1?

Both are half-duplex CAN transceivers in the same 8-SOIC package and AEC-Q100 grade. If your design runs on a 3.3 V CAN controller, the GV variant is the correct choice; for a 5 V-only bus, the HV variant is a drop-in fit.
