Hi,
I want to use a 5V microcontroller to switch up to 12V on and off on the high side of a load. A common way to do this is with an NPN, a P-MOSFET, and a smattering of resistors.
In fact it's so common that I can't help but think there must be an integrated component for it, just as you can buy darlington transistors and pre-biased BJTs. But after poking around on Digi-key for a while, I haven't found such a beast.
Do you know of a component like this?
Thank you,
Bob
