摘要： An overcurrent protection circuit includes a load drive section driving a load, a wire coupled with the load and the load drive section, a current detection section detecting a load current value of an electric current that flows to the load, an addition and subtraction section determining an addition and subtraction value based on the load current value and transmitting an integration result of addition and subtraction, a comparison circuit comparing the integration result with a threshold value, and a control circuit controlling the load drive section based on the comparison result. The addition and subtraction section includes an addition value determination circuit that determines an addition value in the addition and subtraction value based on the load current value and a function expression or information indicating a relationship between the load current value and the addition value.

摘要： A signal generator includes: a current control element for controlling a current flowing through an electric load; and signal forming means for outputting a control signal to the current control element. The signal forming means generates the control signal in such a manner that the current flowing through the electric load has a rising edge and a down edge of a substantially sine waveform. The rising edge of the current is disposed at a timing when the current control element is switched on. The down edge of the current is disposed at a timing when the current control element is switched off.
