Abstract
In some embodiments, a reset circuit for an electronic circuit equipped with a backup power capacitor includes a first detector arranged to detect a predetermined first voltage of the backup capacitor, a second detector arranged to detect a predetermined second voltage of the backup capacitor, the second voltage being lower than the first voltage, and a controller arranged to control an output of a reset request signal based on detection results of the first detector and the second detector. The controller is configured to output the reset request signal when the first detector detects the first voltage after the second detector detected the second detector.
