    Abstract: The invention relates to a high-voltage final output stage (1) for driving an electric load, of the type which comprises a complementary pair (3) of transistors connected between first (Vdd) and second (Vss) supply voltage references, and at least one PMOS pull-up transistor (MP1) connected in series with an NMOS pull-down transistor (MN). The stage (1) comprises an additional PMOS transistor (MP2) connected in parallel with the pull-up transistor (MP1) and having the body terminal in common therewith. More particularly, the body terminals of both PMOS transistors (MP1,MP2) are formed in the semiconductor within a common well which can withstand high voltages, and the additional transistor (MP2) is a thick oxide PMOS power transistor.
