Can anybody plz explain the working of the attached circuit? Its an undervoltage/overvoltage protection with range of 6-11.5 V
my imageviewer program (IrfanView) tell me that it is just a BMP file that is renamed to JPG.
Look - I got a smaller file size![]()

"If the input voltage is too low, Q1 turns on and dumps the gate of Q3 to ground."
As Q3 is a p-channel mosfet, it will turn on in this case and there will be no undervoltage protection
