摘要: The invention concerns a control device comprising circuit generating REF reference voltages (VPOL1, V POL2) three P-type MOS transistors (M12, M13 and M14) connected in series between high-voltage input node (EHV) the earth (GND), supplying on drain source of middle transistor (M13) POL2). Said comprises means for controlling either, first operating mode, to force (M12) current source, second off-state short-circuit third (M14) earth, or, connecting each said diode, their gate being connected, basis logic signal (/WR). Thus, resulting output are based signal.
