A power supply controller includes: a controlling section that, upon determination that no anomaly has occurred, causes a semiconductor switch to execute turning on and, upon determination that the anomaly has occurred, causes the semiconductor switch to maintain an off state; a monitoring section that monitors which condition the controlling section is in, the condition being normal or anormal; and a switching section that, upon monitoring result by the monitoring section indicating the normal condition, causes turning on and off of the semiconductor switch by the controlling section and, upon the monitoring result indicating the anormal condition, causes turning on and off of the semiconductor switch with an external on-off command signals.
Description
technical field [0001] The invention relates to a power supply controller. Background technique [0002] The power supply controller includes a semiconductor switch to be connected between the power supply and the load. The power supply controller turns on / off the semiconductor switch, thereby controlling power supply to the load. This power supply controller has a function for protecting a load circuit and the like without using any fuse element (see Patent Document 1). Specifically, the power supply controller determines whether an overcurrent equal to or greater than a predetermined value passes through the semiconductor switch; and when it is determined that the overcurrent passes, the power supply controller turns on / off the semiconductor switch. Thereafter, when a predetermined period of on-off state occurs, the power supply controller determines that the circuit is short-circuited, and the power supply controller maintains the semiconductor switch in an off state. ...
