Abstract
A high-voltage level shift circuit includes: a first high withstand voltage NMOS transistor driven by an on command; a second high withstand voltage NMOS transistor driven by an off command; a first PMOS current mirror circuit inputting a drain current of the first high withstand voltage NMOS transistor to a reference side; a second PMOS current mirror circuit inputting a drain current of the second high withstand voltage NMOS transistor to a reference side; a first NMOS current mirror circuit inputting an output current of the second PMOS current mirror circuit to a reference side; and an I/V signal conversion circuit receiving an output of the first PMOS current mirror circuit and an output of the first NMOS current mirror circuit to obtain an output control voltage signal.
