Beschreibung
Zusammenfassung:	The invention relates to an electronic circuit (20) comprising a switching means (22), having a monitoring circuit (28) to monitor the switching status of the switching means. According to the invention the switching means comprises at least one semiconductor switch (22) as a switching element, which semiconductor switch (22) is connected to a gate driver (24) which is controlled by a control signal (C) to effect switching of the semiconductor switch, the gate driver (24) being supplied by a gate driver power supply (26), whereby the monitoring circuit (28) is arranged between the semiconductor gate and its collector and comprises a series connection of an opto-coupler (30), a current-limiting resistor (32) and a protection diode (34), which series connection is connected in series with the gate driver power supply (26).
