Key Differentiators
- Integrated CAN FD support up to 5 Mbps (vs MCP2562)
- VIO pin for I/O level shifting (vs TJA1042T/3)
- AEC-Q100 Grade 1 qualification (vs TCAN1042VDR)
Design Notes
Place a 100nF ceramic decoupling capacitor as close as possible to the VCC pin (pin 3) and a 4.7uF bulk capacitor nearby. Keep the CANH and CANL traces short and separated to minimize EMI. Use a 120Ξ© termination resistor at each end of the CAN bus; a split termination with 60Ξ© and 4.7nF capacitor can improve EMC.
The TCAN1042VDRQ1 typically dissipates less than 200mW in normal operation, but at higher bus loads or repeated short-circuit conditions, junction temperature can rise. Ensure adequate copper ground pour on the PCB under the device to help dissipate heat. The thermal resistance of the SOIC-8 package with a 2oz copper plane is roughly 80Β°C/W; verify with IR thermal imaging in production.
Do not leave pin 5 (VIO) floating; connect it to the logic supply of the CAN controller (3.3V or 5V). If VIO is tied to VCC, the device operates at 5V standard. Also ensure the STB pin (pin 8) is pulled low or high as needed; a floating STB may cause unintended silent mode. Always add a series resistor on TXD if required for protection.
