Key Differentiators
- I/O level shifting (VIO pin) for 3.3V/5V logic (vs TCAN1042GVDRQ1)
- Automotive grade (AEC-Q100) (vs TCAN1042VDR)
- CAN FD support up to 5 Mbps (vs TLE6251DS)
Design Notes
Place the TCAN1042VDRQ1 close to the CAN bus connector to minimize stub length. Use a 120Ξ© termination resistor at both ends of the bus. Keep the differential pair (CANH and CANL) tightly coupled and routed with controlled impedance (typically 120Ξ© differential). Add a common-mode choke if EMI is a concern.
Decouple the VCC pin with a 100nF ceramic capacitor placed as close as possible to the pin. The VIO pin should be decoupled with a 100nF capacitor to ground. Ensure the VIO voltage does not exceed VCC to avoid damaging the device. For 3.3V logic, connect VIO to 3.3V.
Do not leave the STB pin floating; tie it to VCC for normal operation or to GND for standby mode. Ensure the TXD pin is not left floating; it should be driven by the CAN controller. When using the device without I/O level shifting (e.g., with TLE6251DS replacement), handle the VIO pin appropriately - connect it to VCC or leave unconnected if not needed.
