Product details

CAN FD transceiver for 5 Mbps automotive buses

5 V supply rail — not 3.3 V logic compatible

If your MCU runs on 3.3 V, you need level translation on the TXD/RXD pins or a CAN transceiver with a separate VIO supply. The 5 Mbps data rate is achievable only with CAN FD controllers that can clock the arbitration phase above 1 Mbps; classic CAN controllers are limited to 1 Mbps.

Active lifecycle and automotive qualification

The AEC-Q100 qualification covers the stress tests required for automotive-grade components: extended temperature cycling, high-temperature operating life, and ESD robustness.

Wettable flank package for AOI

The 8-VSON (3x3) package includes wettable flanks, which allow solder-joint inspection after reflow using automated optical inspection (AOI). This is a practical advantage for automotive production lines where hidden solder joints under a standard DFN would require X-ray.

Frequently asked questions

Does TCAN1051HGDRBRQ1 support CAN FD at 5 Mbps?

Yes, the TCAN1051HGDRBRQ1 is a CAN FD transceiver rated for 5 Mbps data rate. It can handle the faster arbitration and data phases of CAN FD frames, provided the CAN controller on the other side supports FD.

Is TCAN1051HGDRBRQ1 compatible with 3.3 V logic?

Direct connection to a 3.3 V MCU will exceed the input thresholds — use a level shifter or choose a CAN transceiver with a separate VIO pin for 3.3 V logic.

What is the difference between TCAN1051 and TCAN1051H?

The TCAN1051H variant typically offers higher ESD protection or extended bus-fault voltage tolerance compared to the base TCAN1051. For the TCAN1051HGDRBRQ1, the 'H' suffix indicates the higher-performance version with improved bus-pin robustness. Pin-compatible across the family, so a drop-in swap is possible if the PCB layout matches the VSON footprint.
