Abstract: A signal output circuit includes an inverting amplifier circuit, a feedback capacitor and a low pass filter. The inverting amplifier circuit includes an input terminal and an output terminal. The inverting amplifier circuit executes an inverting amplification based on an input signal to output a signal to the output terminal at a pull-up state. An output stage of the inverting amplifier circuit is an open collector or an open drain. The feedback capacitor is connected between the input terminal and the output terminal of the inverting amplifier circuit. The low pass filter has an input and an output. The input of the low pass filter is connected to the output terminal of the inverting amplifier. The output of the low pass filter is connected to the feedback capacitor.

Abstract: A communication circuit apparatus includes: multiple level shift circuits, each of which receives an input signal corresponding to a respective communication bus; an activation comparator for generating an activation signal when the input signal is input into one of the level shift circuits, and a level of the input signal exceeds a predetermined threshold; multiple input current voltage conversion circuits, each of which is arranged together with a respective level shift circuit, converts the input signal to a voltage signal, and outputs the voltage signal as an identification signal; and an identification circuit for identifying one of the communication busses based on the identification signal, which is output from one of the input current voltage conversion circuits. The one of the communication busses corresponds to the one of the level shift circuits, in which the input signal is input.

Abstract: A drive control device includes: an input unit of a command; and a control unit setting a period for rising a current in an inductive load to first and third periods in first and second commands, and setting a period for falling the current to second and fourth periods in the first and second commands, respectively. When the first command is changed to the second command, and at least one middle PMW pulse is disposed between a forward PWM pulse corresponding to the first command and an after PWM pulse corresponding to the second command, the control unit sets fifth and sixth periods in the middle PWM pulse corresponding to the first and second periods of the forward PWM pulse to a length between the first and second periods in the forward PWM pulse and the third and fourth periods in the after PWM pulse, respectively.
