FAE Expert Insights
"The XB-CAN01 is a robust CAN transceiver suitable for automotive and industrial applications. The ±58V fault protection handles wiring faults and transients that would damage lesser transceivers. I find the low standby current particularly valuable for automotive battery-powered systems. The AEC-Q100 qualification provides confidence for automotive designs. EMC performance is excellent - this transceiver passes automotive OEM requirements without additional filtering. For any CAN application requiring reliability, this transceiver is an excellent choice."

Frequently Asked Questions
What is the difference between CAN 2.0 and CAN FD?
CAN 2.0 (Classical CAN) supports data rates up to 1Mbps with 8 bytes data per frame. CAN FD (Flexible Data-rate) increases data rate up to 8Mbps during data phase and supports up to 64 bytes data per frame. XB-CAN01 supports CAN 2.0 at up to 1Mbps. For CAN FD applications, select a CAN FD compatible transceiver. Both use the same physical layer signaling, but CAN FD requires protocol controller support in the MCU.
XB-CAN01 for standard CAN 2.0. Select CAN FD transceiver for higher data rates.
How do I terminate a CAN bus?
CAN bus requires 120Ω termination resistors at both ends of the bus. Use two 120Ω resistors in parallel with the CANH and CANL lines at each physical end. Do not place termination at intermediate nodes. For short networks (<10 meters), a single 120Ω resistor may suffice. For long networks or high speeds, proper termination at both ends is essential. Some transceivers include internal switchable termination for flexibility.
Terminate both ends with 120Ω. Do not terminate intermediate nodes.
What is dominant timeout protection?
Dominant timeout protection prevents permanent bus lockup if a transmitter holds the bus dominant (logic 0) due to hardware or software fault. If the TXD pin remains low longer than the timeout period (typically 1-3ms), the transceiver disables the driver, releasing the bus. This protects the network from a single faulty node. The XB-CAN01 includes this protection, making it suitable for safety-critical applications where bus availability is essential.
Dominant timeout protects against bus lockup. Essential for safety-critical networks.
Can XB-CAN01 operate in industrial temperature range?
Yes, XB-CAN01 is AEC-Q100 Grade 1 qualified, supporting -40°C to +125°C ambient temperature. This industrial/automotive grade ensures reliable operation in harsh environments. The extended temperature range makes it suitable for automotive engine compartments, industrial control cabinets, and outdoor applications. The device specifications are guaranteed across the full temperature range, ensuring consistent performance.
XB-CAN01 suitable for -40°C to +125°C. Ideal for automotive and industrial applications.
How does remote wake-up work on XB-CAN01?
Remote wake-up allows the CAN transceiver to detect bus activity while in low-power standby mode and signal the microcontroller to wake up. In standby mode, XB-CAN01 monitors the bus for dominant states. When valid wake-up patterns are detected, the transceiver drives the RXD pin low to wake the MCU. This enables power-saving sleep modes while maintaining network responsiveness. The MCU can then exit standby and resume normal operation.
Use standby mode for power saving. Remote wake-up maintains network connectivity.
