I want to design an easy power switch that is on by default, but I need the ability to turn the power off.
Is this posible with a few mosfet's?
thanks for any help
The ADP197 is an excellent choice and a lot easier than three MOSFETs. Thank you for recommending it. I had looked at ADI's product list under Power Management (reproduced below), and…
at these current and voltage levels you may want to consider the ADP197.
Connecting the EN pin high through a pull up resistor (10k, 100k) will keep it on but allow you to turn it off by shorting…
