Abstract
Disclosed is a method, a circuit arrangement, and an electronic circuit. The method includes discharging a gate-source capacitance of a transistor device from a first voltage level to a second voltage level with a first resistor connected in parallel with the gate-source capacitance and measuring a first discharging time associated with the discharging, and discharging the gate-source capacitance from the first voltage level to the second voltage level with the first resistor and a second resistor connected in parallel with the gate-source capacitance and measuring a second discharging time associated with the discharging. The method further includes comparing a ratio between the first discharging time and the second discharging time with a predefined threshold, and detecting a fault based on the comparing.
