Hi,
I am asking advice on the following issue:
I need to switch two external power sources ( 5-12 V) and ( -5 to -12V) on and off with a microcontroller (3.3V). The maximum current to expect is around 300 mA.
The first thing that comes to mind is to use ordinary MOSFETs to do this.
Since the quiescent current of the switch must me as low as possible. I was wondering if there is better way to do this.
If MOSFETs are the way to go, is there something to consider to minimize the current consumption.
Attached you find a simple drawing to clarify what I mean.
Thank you very much for any advice!
Peter
