- Sleep mode for low power consumption (vs TCAN1042VDRQ1)
- AEC-Q100 qualified for automotive (vs TJA1463)
Design Notes
Place the TCAN1473A-Q1 close to the CAN bus connector to minimize stub length. Use a 100nF bypass capacitor on VCC and a 10uF bulk capacitor for stable operation. Ensure a solid ground plane under the device to reduce EMI.
Route CANH and CANL as a differential pair with controlled impedance (typically 120 ohms). Keep the traces symmetrical and avoid vias to maintain signal integrity. Add a common-mode choke if the bus is exposed to high EMI environments.
Do not forget to terminate the CAN bus with 120-ohm resistors at both ends. Incorrect termination can cause signal reflections and communication errors. Also, ensure the WAKE pin is properly pulled down if unused, as described in TI E2E forum.
