Abstract: The present invention relates to an electronic fuse device. The electronic fuse device includes: a semiconductor switch and a current monitoring unit. The current monitoring unit is configured to continuously detect a load current flowing through the semiconductor switch during operation and to determine a load current value indicating the load current. The current monitoring unit includes a filter unit for filtering a detection signal detected by the current monitoring unit, and the current monitoring unit includes a correction unit which is configured to determine a measure of dispersion of the load current value and to carry out a correction of the load current value based on the determined measure of dispersion.

Abstract: The present invention relates to a method for checking the switch-off capability of an electronic fuse which is arranged between a voltage source and a consumer. The method includes monitoring a voltage at the consumer, switching the electronic fuse to a non-conductive state, and checking whether the voltage at the consumer drops to a threshold voltage within a set time. The present invention also relates to a system for checking the switch-off capability of an electronic fuse. The system includes a voltage source, a consumer, an electronic fuse between the voltage source and the consumer, a voltage measuring device to measure the voltage at the consumer, and a checking unit. The checking unit monitors the voltage at the consumer via the voltage measuring device, switches the electronic fuse to a non-conductive state, and checks whether the voltage at the consumer drops to a threshold voltage within a set time.
