Abstract

An electronic circuit includes: a drive circuit having an output coupled to a control node of a first electronic switch; a switch circuit with second electronic switches, load paths of the second electronic switches being connected in series, and the switch circuit being connected between a first load node of the first electronic switch and a reference node; and a level shifter coupled between a first signal input and an input of the drive circuit and including cascaded level shifter cells. Each level shifter cell includes a signal input and output, and first and second supply nodes. Each level shifter cell is associated with a respective second electronic switch. The first supply node of each level shifter cell is coupled to a first load node of the associated second electronic switch, and the second supply node is coupled to a second load node of the associated second electronic switch.
