Abstract
An ESD protection circuit comprises a first supply line (V), a second supply line (V), an ESD protection device, preferably being configured as a transistor (M), which is connected between the first and second supply line (V, V) and at least one pin (V) connected to the first and second supply lines (V, V) via diodes D1, D2. The ESD protection device is controllable by a trigger voltage that is set by a trigger voltage setting circuit (R, R, Z1, Z2, Z3). The ESD protection circuit comprises a trigger circuit () being connected to the at least one pin (V) and providing pin specific trigger voltages, wherein the trigger circuit () is further connected to the trigger voltage setting circuit.
