Abstract: A system power supply circuit receives an input voltage VIN, and supplies a power supply voltage to multiple load circuits including a microcomputer. Multiple power supply circuits support the multiple load circuits. An abnormality detection circuit generates an abnormality detection signal that is negated when the input voltage VIN is within, and asserted when it deviates from, the first voltage range, and outputs this signal to the microcomputer. The interface circuit can communicate with the microcomputer. The interface circuit receives a control signal generated by the microcomputer in response to abnormality detection signal assertion, and suspends power supply circuit operation of a channel indicated by the control signal. When the input voltage VIN deviates from a second voltage range defined to be wider than the first voltage range, an internal protection circuit suspends at least one power supply circuit of a predetermined channel.

Abstract: A HEMS controller repeatedly transmits a predetermined signal to a control-target appliance at a set time interval in order to detect a change in a status of the control-target appliance. If the status changes, the HEMS controller notifies a smartphone of the changed status via a server apparatus. In a state where the time interval is set to a first time interval, when receiving a control instruction for controlling an operation of the control-target appliance from the smartphone via the server apparatus, the HEMS controller transmits the control instruction to the control-target appliance. In response to the transmission of the control instruction to the control-target appliance, the HEMS controller changes the time interval to a second time interval shorter than the first time interval.
