Key Differentiators
- VIO pin for direct 3V to 5V MCU interface (vs TJA1051T)
- CAN FD support (vs TJA1042T/3)
- Dual-sourced manufacturing (vs TJA1051T/3)
Design Notes
Place the TJA1051T/3/1 close to the CAN connector to minimize trace length and reduce EMI. Use a 100nF decoupling capacitor on VCC and a 10uF bulk capacitor. Connect the VIO pin to the microcontroller's supply voltage (3.3V or 5V) to ensure proper signal levels. For the CAN bus, use 120-ohm termination resistors at both ends of the network.
Do not connect the VIO pin to a voltage higher than VCC. Ensure the S pin is pulled high or low as needed for normal operation; leaving it floating can cause unintended silent mode. When the supply is off, the TJA1051T/3/1 provides ideal passive behavior, but verify that the bus is not loaded by other components. Use proper ESD protection on the CANH and CANL lines.
The TJA1051T/3/1 typically dissipates low power, but in high-temperature environments, ensure adequate PCB copper area for heat dissipation. The SO-8 package has a thermal resistance of approximately 150 C/W (theta_JA). For continuous operation at 150C ambient, calculate the junction temperature to ensure it stays within the absolute maximum rating.
