DATASHEET ISL6185 FN6937 Rev 3.00 Dual USB Port Power Supply Controller March 8, 2012 The ISL6185 USB power controller family provides fully Features independent overcurrent (OC) fault protection for two or more 2.5V to 5V Operating Range USB ports. 71m Integrated Power P-channel MOSFET Switches This product family consists of sixteen individual functional product variants and three package options. It is operation Continuous Current Options for 0.6A, 1.1A, 1.5A and 1.8A rated for a nominal +2.5V to +5V range and is specified over Thermally Insensitive 12ms of Current Limiting Prior to the full commercial and industrial temperature ranges. Turn-Off Each ISL6185 type incorporates in a single package two Output Discharges with Reverse Current Blocking When 71m P-channel MOSFET power switches for power control. Disabled Each features internal current monitoring, accurate current limiting, and current limited delay to turn-off, for system Latch-off or Auto Restart Options supply protection along with control and communication I/O. 1A Off-State Supply Current The ISL6185 family offers product variants with specified Enable Polarity Options continuous output current levels of 0.6A, 1.1A, 1.5A or 1.8A Industry-standard Pin for Pin SOIC, and Smaller DFN enable active high or low inputs and latch off or automatic retry Packages Available after overcurrent turn-off, making these devices well suited for many low-power applications. UL Recognized, File Number: E333469 This family of ICs is offered in an industry-standard SOIC Applications pinout and also in the 70% smaller 3x3 DFN packages providing similar or enhanced performance in the smallest USB 1, 2, 3 Port Power Management possible package.
