Electric power supply control circuit |
摘要 |
An electric power supply control circuit includes a bypass circuit connected in parallel with a semiconductor switch. Upon a control circuit being in an inactive state while a load being in a non-electrifying state or in a standby state, the bypass circuit connects a power source to the load. The bypass circuit includes a electrifying decision circuit that generates an activation signal for activating the control circuit in accordance with the load being put in an operation state. The electrifying decision circuit supplies the activation signal to the control circuit so as to turn on the semiconductor switch and allow electric power supply to the load through an electrifying line. |

1. An electric power supply control circuit to be connected to an electrifying line that supplies electric power from a power source to a load, the electric power supply control circuit including a semiconductor switch and a control circuit, the semiconductor switch being for turning on and off supply of the electric power, and the control circuit being for controlling turning on and off of the semiconductor switch while protecting the semiconductor switch and the electrifying line;
the electric power supply control circuit comprising: a bypass circuit connected in parallel with the semiconductor switch, wherein, upon the control circuit being in an inactive state while the load being in a non-electrifying state or in a standby state, the bypass circuit connects the power source to the load, wherein: the bypass circuit includes a electrifying decision circuit that generates an activation signal for activating the control circuit in accordance with the load being put in an operation state, wherein the electrifying decision circuit supplies the activation signal to the control circuit so as to turn on the semiconductor switch and allow electric power supply to the load through the electrifying line.
