Abstract:
A semiconductor device includes a power semiconductor switching element, a comparator circuit, a filter circuit and an erroneous-detection prevention circuit. The comparator circuit compares a value of an output voltage of the switching element with a threshold and outputs a comparison result as a determination signal. The filter circuit outputs the determination signal to the control circuit after a delay time required for the output voltage of the switching element to reach a predetermined voltage value for determining that the switching element is in a normal ON state after the switching element is turned on. The erroneous-detection prevention circuit changes a turn-on time of the switching element, the delay time, or a voltage value of the determination signal when a voltage of the power supply drops in a case where the switching element is normally turned on.

Claim (Index 7):
The semiconductor device according to  claim 6 ,\n wherein the erroneous-detection prevention circuit further includes:\n an internal ground circuit provided between an internal ground of the charge pump circuit and an external ground of the semiconductor device and configured to draw electric charge of the internal ground to the external ground when the voltage of the power supply drops, so as to decrease a potential of the internal ground to stabilize an output of the charge pump circuit.
