Abstract
A voltage detector includes a comparison unit which is equipped with a plurality of comparators and which is configured to compare a threshold voltage and determination voltages corresponding to each comparator and output a first result of High or Low for each comparator and configured to compare an input voltage and the determination voltages and output a second result of High or Low for each comparator, and a determination unit configured to determine based on the first result and the second result whether or not the input voltage is less than or equal to the threshold voltage.
Claims8
A voltage detector, comprising:
- a comparison unit having a plurality of comparators, said comparison unit configured to compare a threshold voltage and determination voltages corresponding to said each comparator and output a first result of High or Low for each comparator, and configured to compare an input voltage and the determination voltages and output a second result of High or Low for each comparator;
- and
- a determination unit configured to determine based on the first result and the second result whether or not the input voltage is less than or equal to the threshold voltage.
A method for detecting a voltage, comprising the steps of:
- comparing, using a plurality of comparators within a comparison unit, a threshold voltage and determination voltages corresponding to each of the comparators and outputting a first result of High or Low for each comparator;
- comparing, using the comparison unit, an input voltage and the determination voltages and outputting a second result of High or Low for each comparator;
- and
- determining, using a determination unit, based on the first result and the second result whether the input voltage is less than or equal to the threshold voltage.
