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.
Features
• 2.5V to 5V Operating Range
• 71mΩ Integrated Power P-channel MOSFET Switches
• Continuous Current Options for 0.6A, 1.1A, 1.5A and
