Intersil USB Dual Channel Power Supply Controller
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 and is operation rated for a nominal +2.5V to +5V range and 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 and 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 over current turn-off making these devices well suited for many low power applications.
This family of ICs is offered in an industry std. SOIC pinout and also in the 70% smaller 3x3 DFN packages providing similar or enhanced performance in the smallest possible package.
