WebJun 8, 2024 · Figure 2: A poly fuse. As the current flow increases, the particles inside the fuse will start moving fast. The slow motion of these particles are the ones keeping a smooth current flow across the fuse. When the particles are moving rapidly, it will oppose the current flow through them. Imagine a situation where a short circuit happens. WebA fuse acts as a circuit breaker to protect against overload by interrupting the power flow. Typically, the fuse element is a thin wire with a low melting point. Higher power through the fuse means more increased current flow through it, which heats the wire and causes it to melt or blow. This interrupts the power flow. WebA novel programmable element has been developed and evaluated for state of the art CMOS processes.
