You're correct that SiC is for medium to high voltage. But there's also GaN, which is for low to medium voltage, and already works in the millivolt range. Both GaN and SiC will have wider ranges in the future as the technology con

You're right that the product number is not a very meaningful value. https://en.wikipedia.org/wiki/Risk_matrix Take a look at this risk matrix. It's divided into cells that are each assigned a category. If yo

The product indirectly tells you the criteria for accepting the risk as-is, but it doesn't give you any insight into how to reduce the risk. That's what severity and likelihood are for. You need all three together.

The general discussion is about Ada ... GP said it depends on what the language does with that concept, and then I linked some extra info about what Ada and SPARK do with the concept. As for whether it's useful ... it's absolutely

https://www.adaic.org/resources/add_content/standards/05rat/... Interesting history of how there was supposed to be a difference, but the idea was dropped and then later revived by SPARK.

You can use an MCU as a controller. Here's an example. https://youtu.be/m8rK9gU30v4 The problem is that you can't make every controller with an MCU, and you can't always make a competitive controller with an

The supporting ICs are the same. For now, at least. But because of differences between GaN and Si, the selection of reasonably compatible controllers and gate drivers is smaller. For example, many ICs made for Si are underperformers for GaN

Here's an interesting video series describing such a software-configured, hardware-controlled switching controller. Here, Microchip markets this particular line of PIC MCUs as a "field-programmable switch-mode power controller&quo
