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).

Abstract: In an integrated circuit, a detection device detects a drop in the supply voltage of the core of the integrated circuit or an excessively slow build-up of this voltage with respect to a supply voltage of the input/output interface circuits of the integrated circuit. Outputs of the interface circuits are set to a high impedance state by the detection device to minimize their power consumption.
