Inrush current suppression circuit and power supply circuit

摘要

PROBLEM TO BE SOLVED: To provide a rush current control circuit in which environmental resistance is improved, and electronic equipment using the rush current control circuit.;SOLUTION: The present invention provides a rush current control circuit arranged between a power source and a load circuit. The rush current control circuit includes: a first line electrically connected to one of a power source potential and a ground potential; a second line electrically connected to the other of the power source potential and the ground potential; a reactor inserted into the first line; a transistor inserted into the second line; a thermistor electrically connected to the transistor in parallel; a partial pressure resistance that electrically connects between the first line and the second line, and applies a voltage occurred in the first line and the second line to a gate of the transistor while parting the pressure; and a diode that electrically connects between a node in the load circuit of the transistor and the node of the power source of the reactor.;SELECTED DRAWING: Figure 4;COPYRIGHT: (C)2018,JPO&INPIT
