Abstract:
1. An operation controller comprising: a reference voltage generator, which is connected to an enable terminal to which an enable signal is to be supplied, and configured to increase a reference voltage in response to a start signal after supplying of the enable signal until the reference voltage is increased to a stable value, and to generate a stop signal after the reference voltage has risen to the stable value; a starter circuit configured to generate the start signal supplied to the reference voltage generator when the enable signal is supplied to the enable terminal, and terminate the start signal when the enable signal is no longer supplied or the stop signal is generated; and a switch element, which has a first end connected to the enable terminal and a second end configured for connection to a prescribed voltage, and which is configured to be turned on when the start signal is generated and turned off when the start signal is terminated.
