5.3 A electronic fuse for 2.7 V to 18 V rails
It replaces a discrete hot-swap controller plus MOSFET in a single 20-WFQFN package with exposed pad, covering common 3.3 V, 5 V, 12 V, and 15 V supply rails.
The ±8% accuracy on the current-limit threshold means a 5.3 A setting trips between roughly 4.9 A and 5.7 A. That guard band matters when the load inrush or transient peak sits close to the limit — budget the tolerance so the fuse does not nuisance-trip on normal start-up current.
