Abstract
In a semiconductor device, a high-side potential determination circuit outputs an event signal when a high-side reference potential detected by a high-side potential detection circuit rises. If at that time an input logic signal for controlling a high side is at a low (L) level, a pulse generation circuit regenerates a reset signal for a high-side drive circuit. When the input logic signal for controlling the high side is at the L level and the event signal is inputted, an overcurrent detection determination circuit makes an overcurrent detection signal from an overcurrent detection circuit invalid. When the event signal is not inputted, the overcurrent detection determination circuit makes the overcurrent detection signal valid.
