Using MOSFET to switch dual power supply with common ground as a PWR/GND DPST switch for each power line
I have started a new project, an automatic firing system for fireworks, powered by 2 lead-acid batteries (12V). The batteries are connected in series with a common ground (GND), so the power ...

What MOSFETs should I use in this configuration?
Here is a configuration of MOSFETs which I believe allows for two different sources to supply power to the same load.
This diagram was originally found here.
The primary source is connected to the ...

How to increase the output current of a dual supply (virtual ground) circuit
I need to build a dual 5 volts power supply capable of 200mA output current.
I've seen designs using TLE2426 and BUF634, but they cost too much for my project.
Is it possible to use a simple OpAmp ...
