DESCRIPTION

· The ISL6186 USB power controller family provides overcurrent (OC) fault protection for one or more USB ports.
· It consists of eight functional variants and three package options, operating within a +2.5V to +5V range.
· Features include a 45mΩ P-channel MOSFET power switch, internal current monitoring, and accurate current limiting.
· Offers continuous output current levels of 1.5A, 3A, or 3.6A with options for latch-off or automatic retry after overcurrent turn-off.
· Available in SOIC and smaller 3x3 DFN packages, with the DFN package including a Power-Good output feature.
