Key Differentiators
- CAN FD support up to 5 Mbps (vs TCAN337)
- Bus fault protection up to Β±58 V (vs SN65HVD232)
- Standby mode for low power (vs SN65HVD232)
Design Notes
Place the TCAN337G close to the CAN connector to minimize trace length and reduce EMI. Use a 100 nF bypass capacitor close to the VCC pin and a 10 Β΅F bulk capacitor on the supply. Ensure a solid ground plane for the CAN bus and transceiver.
Always terminate the CAN bus with 120 Ξ© resistors at both ends to prevent signal reflections. Incorrect termination can cause communication errors. Also, ensure the STBY pin is properly controlled to avoid unintended standby mode.
The TCAN337G has thermal shutdown protection, but ensure adequate PCB copper for heat dissipation in high-temperature environments. The SOT-23-8 package has limited thermal capacity, so avoid continuous operation at maximum bus fault conditions.
