Design Notes
Although CAN transceivers typically operate at low power, thermal dissipation can become significant in high-temperature environments. Ensure the SOIC-8 package has adequate copper pour on the PCB to spread heat, especially when operating at the upper end of the -55°C to 125°C range. The junction-to-ambient thermal resistance (ThetaJA) is [DATA_NEEDED], but typically around 100-150°C/W for SOIC-8. Design accordingly to keep the junction temperature below the maximum rating.
Place a 100 nF ceramic capacitor and a 10 uF electrolytic capacitor as close as possible to the VCC pin to provide low-impedance decoupling. Use a solid ground plane under the transceiver. Route the CANH and CANL traces as a differential pair with controlled impedance (typically 120 ohms). Keep the bus traces away from noisy digital lines to avoid coupling. Termination resistors (120 ohms) should be placed at both ends of the CAN bus.
One common pitfall is running the CAN bus without proper termination, which causes signal reflections and communication errors. Also, ensure the supply voltage does not exceed the maximum rating; the TCAN1042GVDRQ1 is typically designed for 4.5V to 5.5V, but verify the exact range from the datasheet. Do not omit the I/O level shifting voltage reference (if applicable) when interfacing with 3.3V controllers, as this will cause logic-level incompatibility.
Compliance Information
