Abstract
A circuit device, made up of a reduced number of components, for simultaneously turning on a plurality of power transistors, being of a type adapted to be connected between the output of an oscillator and the bootstrap input of a turn-on circuit which are both incorporated into an integrated circuit also incorporating said transistors, further comprises: PA0 a first capacitor having one end connected to the oscillator output and the other end connected to the bootstrap input via a diode, PA0 a second capacitor connected between the bootstraps input and one voltage supply pole, and PA0 a second diode connected between the junction of the first capacitor and the diode, and the voltage supply pole.
