Hello.
Question about the fan speed controller.
I hope the place I posted is right.
My customer wants to control the fan with the CPU.
The customer wants to know the speed of the fan, but at the same time, they want to not burden the CPU.
They want the ability to monitor the tachometer output.
This function sends a rise (or fall) to the CPU when the speed drops below a set speed, and it is hoped that other functions will not be compounded as much as possible (the customer only wants pure monitoring of the rpm).
The customer has already considered MAX31790, but is frustrated that this device does not purely output rpm errors.
Is there a suitable device for this desire?
It can be a product that is not included in the fan speed controller category.
Thank you and best regards,
