Abstract: A protection device includes a switching transistor (M11), connected between the gate of the output transistor (TS1) and ground, and a control circuit (CM), connected to the gate of the switching transistor (M11), which are capable of ensuring that the switching transistor (M11) is off when there is no electrostatic discharge at the drain of the output transistor (TS1) and capable of turning the switching transistor (M11) on when there is an electrostatic discharge at the drain of the output transistor (TS1).
