Drivers, Receivers, Transceivers Procurement Notes

Verify that the ordering suffix /V+T denotes automotive qualification and tape-and-reel packaging. Confirm the specific revision level matches design requirements. Ensure compatibility with existing PCB footprints for the 14-pin SO package. Check for lead-free/RoHS compliance status if required by local regulations.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring robust fault protection against high-voltage transients on the CAN bus. It is suitable for permanent battery-supplied modules where low-power sleep modes are critical. Ensure the system voltage ranges align with the specified VCC, VI/O, and VBAT limits. Consider the thermal performance within the -40°C to +125°C operating range.

Drivers, Receivers, Transceivers FAQ

How does the MAX13041 manage power consumption in sleep mode?

In sleep mode, the device disables the CAN transmitter and receiver while enabling a low-power receiver to monitor the bus. It also drives the INH pin to high impedance, disabling one or more external voltage regulators to minimize power draw.

What is the purpose of the SPLIT pin?

The SPLIT pin outputs a stabilized DC voltage of VCC/2 during normal operation. Connecting this pin to the center node of split termination resistors stabilizes the common-mode voltage of the bus, reducing electromagnetic emissions caused by common-mode voltage steps.

How is the Wake-on-CAN feature triggered?

Wake-on-CAN is triggered by detecting two dominant bus cycles, each followed by a recessive bus cycle. This remote wake-up request sets the wake-up flag, allowing the device to restore power to the node.
