  • Apparatus for detecting current
    Patent number: 10509059
    Abstract: The apparatus for detecting current includes: a charging stage having one end connected to a power source and another end connected to an inductor and configured to charge the inductor with a current; a discharging stage having one end connected to the inductor and another end connected to ground potential and configured to discharge the current charged in the inductor; and a detecting stage configured to detect a magnitude of a current flowing through the inductor based on a first output voltage output from a first output node of the charging stage when the inductor is charged by the charging stage or on a second output voltage output from a second output node of the discharging stage when the inductor is discharged by the discharging stage.
