  • Supports CAN FD up to 2 Mbps (vs NCV7342)

Design Notes

Place the TCAN1051HVDQ1 close to the CAN connector to minimize stub length. Use a 120 Ω termination resistor at each end of the bus. For split termination, connect the SPLIT pin to the center tap of the termination resistors. Ensure a solid ground plane under the device to reduce EMI.

Bypass the VCC pin with a 100 nF ceramic capacitor placed as close as possible to the pin. Additionally, a 10 µF bulk capacitor may be needed if the supply is shared with other loads. The device operates from 4.5V to 5.5V, so ensure the supply is within this range under all conditions.

Do not exceed the absolute maximum ratings, especially the fault voltage on CANH and CANL (±58 V). Ensure the silent mode pin (S) is properly controlled to avoid unintended bus access. Also, verify that the microcontroller's CAN controller is compatible with the transceiver's timing requirements.
