Dual USB Port Power Supply Controller

ISL6185

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.
