- AEC-Q100 qualification (vs TCAN337GDR)
- Higher bus fault protection (vs SN65HVD230)
Design Notes
Place the TCAN337G-Q1 close to the CAN bus connector to minimize stub length. Use a 120Ω termination resistor at both ends of the bus. Ensure the ground plane is solid and continuous under the device to reduce noise. Keep the CANH and CANL traces parallel and close together to minimize loop area and reduce EMI.
Decouple the VCC pin with a 100nF ceramic capacitor placed as close as possible to the pin. Additionally, a 10µF bulk capacitor may be needed if the supply is shared with other components. The VIO pin should be connected to the same supply as the CAN controller to ensure proper logic levels. Use a 0.1µF capacitor on VIO if the supply is noisy.
Do not exceed the absolute maximum ratings, especially the bus fault voltage of ±58V. Ensure the STB pin is properly controlled to avoid unintended silent mode. When using CAN FD, verify that the loop delay symmetry meets the requirements for the data rate. Also, ensure the VIO voltage does not exceed VCC to prevent damage.
