Abstract
The electronic device for protecting against a polarity reversal of a DC power supply voltage comprises, produced within one and the same integrated circuit, an N-channel main transistor (TP) mounted on the line of expected positive polarity of the power supply voltage and command means (MCM) for the main transistor comprising a charging pump circuit (CP), associated with a dynamic biasing circuit (MCTRL) for the substrate regions of active components connected to the main transistor.
