ELECTRONIC APPARATUS
Document Type and Number:
Japanese Patent JP2020145907
Kind Code:
A
Abstract:
To suppress the current interruption by an electronic fuse.SOLUTION: An electronic apparatus includes a power supply that powers a load 20, an electronic fuse 1 that is provided between the power supply and the load 20, and cuts off a current on condition that the resistance value of the load 20 is equal to or less than an allowable minimum resistance value determined on the basis of a voltage applied from the power supply before a predetermined time elapses after the power supply has started generating power, and cuts off the current on condition that a reference current value flows after the predetermined time has passed since the power supply has started the generation of power, and supplies a current less than the reference current value to the load, and a delay circuit 2 that is provided between the electronic fuse 1 and the load 20 and delays timing at which the electronic fuse 1 supplies a current to the load 20.SELECTED DRAWING: Figure 1
