- Higher bus fault voltage (vs SN65HVD230DR)
- Smaller package option (vs TCAN337GD)
Design Notes
Place the TCAN337G close to the CAN bus connector to minimize trace length and reduce EMI. Use a 100 nF bypass capacitor close to the VCC pin and a 10 µF bulk capacitor on the supply rail. Ensure a solid ground plane under the device for thermal and electrical performance.
Do not forget to include proper bus termination resistors (120 Ω) at both ends of the CAN bus. Incorrect termination can cause signal reflections and communication errors. Also, ensure the STBY pin is properly controlled to avoid unintended standby mode.
The TCAN337G in SOT-23-8 package has limited thermal dissipation capability. For high-power applications, ensure adequate PCB copper area for heat sinking. The device's thermal shutdown protection will activate if the junction temperature exceeds the limit, so design for proper airflow or heat dissipation.
Compliance Information
RoHS compliant per TI product page. Not AEC-Q100 qualified; for automotive, consider TCAN337G-Q1.
