Fuse programming circuits, devices and methods. In some embodiments, a fuse circuit can include a fuse pad configured to receive a voltage, a fuse having a first end coupled to the fuse pad and a second end coupled to a switching element configured to enable a current to pass from the fuse pad to a ground potential.

A protection device comprises a first planar substrate, a second planar substrate, a heating element, a fusible element and an absorbent element. The first substrate comprises a first surface, and the second substrate comprises a second surface facing the first surface. The heating element is disposed on the first surface, and the fusible element is disposed above the heating element. The absorbent element is disposed on the second surface and above the fusible element. When over-current or over-temperature occurs, the heating element heats up to melt and blow the fusible element and the absorbent element absorbs melted metal of the fusible element.

An in-vehicle device of the present invention includes a fuse and an upstream capacitor having one end connected to a connection node upstream of the fuse in a current path of current that flows through the fuse. One end of a downstream capacitor is connected to a connection node downstream of the fuse in the current path. A determiner determines whether or not the fuse is blown based on an upstream voltage that passed through the upstream capacitor and a downstream voltage that passed through the downstream capacitor.

A method for operating a protective apparatus and a protective apparatus, in particular a self-tripping explosive fuse, wherein the protective apparatus includes a fuse element, which is designed to interrupt a conductor section by an explosion. A tripping unit is designed to trip the explosion by an ignition voltage (U.sub.Z) when the ignition voltage exceeds a prescribed value. The protective apparatus has a thermoelectric element, which generates the ignition voltage (U.sub.Z) depending on heating of the conductor section.

A fuse has a first contact and a second contact, with the second contact being used to electrically contact the device to be protected. The fuse has a fuse element that connects the first contact to the second contact. The fuse also has an additional contact being arranged so as to be insulated from the first contact and insulated from the second contact and, in an untripped state, is contactless with respect to the fuse element, with the first contact being directly connected to the first potential during operation and with the device to be protected being directly connected to the second potential during operation, with the additional contact also being directly connected to the second potential during operation. A fourth contact makes external triggering available, with triggering resulting in an electric arc that causes the fuse element to fuse.
