Abstract
An electronic apparatus includes: a power supply circuit that supplies power supply voltage to a load; an overcurrent detection circuit that performs output of detection information indicating the direction of current at a power supply path for the load in the power supply circuit when overcurrent occurs in the power supply path; and a determination circuit that performs output of notification information indicating whether or not a location at which a failure occurs exists within the power supply circuit or outside the power supply circuit, based on the detection information.
