原标题：Intersil ISL6185双路USB电源控制解决方案

　　Intersil 公司的ISL6185是具有过流(OC)故障保护的双路或多路USB电源控制器，工作电压2.5V-5V。器件集成了两个用两个用于功率控制的71mΩ P沟MOSFET功率开关，连续电流选择为0.6A, 1.1A, 1.5A和1.8A，关断电流1uA，主要用在USB 1, 2, 3 端口电源管理，和低功率(18W)电路限流和中断器。本文介绍了ISL6185主要特性，简化方框图，典型应用框图以及ISL61851EVAL1Z评估板电路图和材料列表。

　　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.
