AM4372: Part number request for processor/microcontroller to be used as a heater

 Hello Drew Nakamura

Thank you for the query.

I am not sure we have any devices that i could recommend out of the Sitara family of processors that could run out of a single supply.

I am not sure if there is an MCU family that could dissipate 5..10 W.

Are you able to share additional details on the requirement.

You may have alternate ways to generate the constant heat and is this something you have considered.

Hi Sreenivasa, 

Thanks for getting back to me. The single supply requirement is not that critical, but it would help simplify the design a bit. 

The main goal is to create a constant power (heater) circuit that also has a temperature sensing capability. I discuss my current approach in the link below, but I wanted to see if there was a was a way to achieve a similar function in a smaller footprint. My current approach will also have a thermistor nearby for temperature sensing, but if there was a device that could dissipate heat and sense its own temperature that would provide the fastest response time. Both of these considerations led me to thinking a microcontroller running a stress test indefinitely might be able to achieve this, but I realize this is not a very realistic application. 

I don't have a specific footprint requirement right now for the circuit, I'm still just exploring my options. I just wanted to see if you might know of a part off the top of your head that could work for this, but if not then no problem.

Hello Drew Nakamura

Thank you.

I am not aware of any of the Sitara processor family device that could perform the stated function.

Let me check with the expert and update you.
