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 45m?/SPAN> 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.
