5.3 A electronic fuse with 2.7 V to 18 V input range
It is designed for hot-swap, overcurrent, and short-circuit protection on supply rails from 2.7 V up to 18 V, covering the common 3.3 V, 5 V, and 12 V buses used in industrial and telecom equipment. The continuous output current rating is 5.3 A, which sets the load budget for the protected rail. The ±8% accuracy on the current-limit threshold means the nominal trip point must be set with headroom above the worst-case load current to prevent nuisance tripping — a 5 A continuous load on a 5.3 A limit leaves only 6% margin, so the designer should account for the full ±8% tolerance band.
Mounting is surface-mount only, with the exposed pad as the primary heat path.
This removes the last-time-buy risk for new designs and production ramps.
