USB Port Power Supply Controller
ISL6186
The ISL6186 USB power controller family provides
overcurrent (OC) fault protection for one or more USB ports.
This product family consists of eight 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 ISL6186 type incorporates a 45mΩ P-channel MOSFET
power switch 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 ISL6186 family offers product variants with specified
continuous output current levels of 1.5A, 3A or 3.6A, enable
active high or low inputs, and latch off or automatic retry after
overcurrent turn-off, making these devices well suited for many
low-power applications.
This family of ICs is offered in an industry standard SOIC package
as well as in the 70% smaller 3x3 DFN package, which provides
the same performance and an additional Power-Good output
feature in the smallest possible (10 Ld DFN) package.
Features
• 2.5V to 5V Operating Range
• 45mΩ Integrated Power P-channel MOSFET Switches
• Continuous Current Options for 1.5A, 3A and 3.6A
• Thermally Insensitive 12ms of Current Limiting Prior to
Turn-Off
• Output Discharges with Reverse Current Blocking When
Disabled
• Latch-off or Auto Restart and Enable Polarity Options
• 1µA Off-State Supply Current
• Industry Standard Pin-for-Pin SOIC and Smaller DFN
Packages Available
Applications
• USB Port Power Management Including USB 3.0
• Low Power Electronic Circuit Limiting and Breaker

NOTES:
4. θJA is measured with the component mounted on a high effective thermal conductivity test board in free air. See Tech Brief TB379 for details.
5. θJA is measured in free air with the component mounted on a high effective thermal conductivity test board with “direct attach” features. See Tech
Brief TB379.
6. For θJC, the “case temp” location is the center of the exposed metal pad on the package underside.
7. All voltages are relative to GND, unless otherwise specified.
Electrical Specifications VIN = 5V, TA = TJ, Unless Otherwise Specified. Boldface limits apply over the operating temperature
range, 0°C to +75°C or -40°C to +85°C.
