Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix, such as .RDG, which indicates green material type and tape-and-reel packaging configuration. Confirm that the supplier provides documentation verifying AEC-Q100 qualification status. Ensure the received components match the marking code K9125P WWXXG to validate authenticity and traceability against the manufacturer's official release specifications.

Drivers, Receivers, Transceivers Selection Notes

Select this transceiver when designing systems requiring high-speed CAN FD communication up to 5Mbps alongside significant bus fault tolerance. The integrated ESD and surge protection eliminates the need for external suppressors. Ensure the microcontroller interface voltage falls within the 1.7V to 5.5V VIO range for direct compatibility without level shifting circuitry.

Drivers, Receivers, Transceivers Part Context

This component belongs to the family of high-speed CAN transceivers designed for harsh electromagnetic environments. It integrates physical layer signaling with advanced protection mechanisms, distinguishing it from standard transceivers that require external protection components. The design focuses on reducing bill-of-materials complexity while maintaining compliance with stringent automotive transient standards.

Drivers, Receivers, Transceivers FAQ

How does the AZKN9125P handle TXD dominant state failures?

It utilizes a TXD dominant time-out function that automatically turns off the driver if the TXD pin remains low longer than the specified timeout period, releasing the bus to prevent permanent blockage.

What is the common-mode input range for the receiver?

The receiver supports a common-mode voltage range of -40V to +40V on the CANH and CANL pins during both normal and standby modes.

Does the device support passive behavior when power is off?

Yes, the AZKN9125P exhibits ideal passive behavior to the CAN bus when supply power is off, ensuring it does not interfere with other nodes on the network.
