Abstract
An electro-static discharge protection circuit including: a first input terminal and a second input terminal; a first output terminal coupled to the first input terminal, and a second output terminal coupled to the second input terminal; a first circuit branch connected between the first input terminal and the second input terminal, said first circuit branch including at least one first Zener diode having a cathode terminal and an anode terminal; a second circuit branch connected between the first output terminal and the second output terminal, wherein the first circuit branch comprises a load element coupled between the second input terminal and the anode terminal of the at least one first Zener diode; the second circuit branch includes a first transistor having a control terminal adapted to receive a transistor control voltage, the first transistor being coupled to the load element so as to receive from the load element the transistor control voltage.
