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