Abstract
A device for detecting a change in voltage across a switch includes a resistive-capacitive network and a timer circuit. The resistive-capacitive network includes an impedance, a first resistive element, and a first capacitive element to provide a signal representative of a voltage across the switch. The timer circuit generates a detection signal that is representative of the change in the voltage across the switch after switching on of the switch. The timer circuit raises a level of the detection signal if the voltage across the switch does not fall below a predetermined value after switching on of the switch. The resistive-capacitive network is configured such that parasitic capacitances of the device are compensated or over compensated so as to prevent the timer circuit from raising the level of the detection signal if the voltage across the switch does fall below the predetermined value after switching on of the switch.
