Semiconductor device

A semiconductor device comprising

• an input determination circuit that includes:
• a comparator that is driven based on a first reference potential and includes an input voltage terminal and a reference voltage terminal;
• a reference voltage generation circuit that inputs a reference voltage that is generated from a connection point between a constant current source and a resistor to the reference voltage terminal of the comparator, the constant current source and the resistor being interposed between a second reference potential that is separated from the first reference potential and a third potential that is higher than the first reference potential and the second reference potential;
• a second low pass filter that is interposed between a signal input system that is connected to the input voltage terminal of the comparator and the first reference potential;
• and
• a third low pass filter that is interposed between a reference voltage system between the reference voltage generation circuit and the reference voltage terminal and the first reference potential.
