The ISL6185 USB power controller family provides fully

independent overcurrent (OC) fault protection for two or more

USB ports.

This product family consists of sixteen individual functional

product variants and three package options. It is operation

rated for a nominal +2.5V to +5V range and is specified over the

full commercial and industrial temperature ranges.

Each ISL6185 type incorporates in a single package two 71mΩ

P-channel MOSFET power switches for power control. Each

features internal current monitoring, accurate current limiting,

and current limited delay to turn-off, for system supply

protection along with control and communication I/O.

The ISL6185 family offers product variants with specified

continuous output current levels of 0.6A, 1.1A, 1.5A or 1.8A; enable

active high or low inputs; and latch off or automatic retry after

overcurrent turn-off, making these devices well suited for many

low-power applications.

This family of ICs is offered in an industry-standard SOIC pinout

and also in the 70 smaller 3x3 DFN packages providing similar

or enhanced performance in the smallest possible package.
