A simple and inexpensive ideal-diode MOSFET circuit
by Crutschow When you parallel a battery with another battery or other source, the batteries are often required not be back charged. This can be done with standard diodes, but that gives close to a half volt drop — even with Schottky diodes. This is especially problematic with low-voltage batteries, where that drop is a […]
