Abstract
A semiconductor device includes an external terminal, a switching output stage that performs switching drive of a terminal voltage at the external terminal, an output control unit arranged to generate a drive signal for the switching output stage according to an input pulse signal, a counter arranged to count the number of pulses of the input pulse signal so as to generate a mask signal, a logical gate arranged to mask the input pulse signal according to the mask signal, and a comparator arranged to compare the terminal voltage with a predetermined threshold value voltage so as to generate a reset signal of the counter.
