1. An electronic circuit, comprising:
a first circuit configured to generate a first current and output a first voltage, the first voltage being one of:
a voltage based on the first current, and
a first predetermined voltage;
a second circuit configured to generate a first output current based on the first voltage;
a first output terminal outputting the first output current to a first switching device;
a first input terminal having a first input signal inputted, the first input signal relating to driving and non-driving of the first switching device;
a third circuit configured to generate a first control signal based on the first input signal, the first control signal switching the first voltage to the first predetermined voltage and stopping the first current;
a fourth circuit configured to generate a second current; and
a fifth circuit configured to convert the second current into an input voltage, wherein
the first circuit is configured to generate the first current corresponding to the second current based on the input voltage.
