Dual USB Port Power Supply Controller
ISL6185
Features
The ISL6185 USB power controller family provides fully
independent overcurrent (OC) fault protection for two or more
USB ports.
• 2.5V to 5V Operating Range
• 71mΩ Integrated Power P-channel MOSFET Switches
• Continuous Current Options for 0.6A, 1.1A, 1.5A and 1.8A
This product family consists of sixteen individual functional
product variants and three package options. It is operation
rated for a nominal +2.5V to +5V range and is specified over the
full commercial and industrial temperature ranges.
• Thermally Insensitive 12ms of Current Limiting Prior to
Turn-Off
• Output Discharges with Reverse Current Blocking When
Disabled
Each ISL6185 type incorporates in a single package two 71mΩ
P-channel MOSFET power switches for power control. Each
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.
• Latch-off or Auto Restart Options
• 1µA Off-State Supply Current
• Enable Polarity Options
• Industry-standard Pin for Pin SOIC, and Smaller DFN Packages
Available
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
overcurrent turn-off, making these devices well suited for many
low-power applications.
• UL Recognized, File Number: E333469
Applications
• USB 1, 2, 3 Port Power Management
This family of ICs is offered in an industry-standard SOIC pinout
and also in the 70% smaller 3x3 DFN packages providing similar

ISL6185
Introduction
Functional Description
The ISL6185 is a dual channel fully independent overcurrent (OC)
fault protection IC for the +2.5V to +5V environment. Each
ISL6185 incorporates in a single package two 85mΩ P-channel
MOSFET power switches for power control. Independent enabling
inputs and fault reporting outputs compatible with 2.5V to 5V
logic allow for external control and reporting. This device features
integrated power switches with current monitoring, accurate
current limiting, reverse bias protection and current limited
timed delay to turn-off for system reliability. See Figures 13
through 28 for typical operational waveforms including both
under-current and over-current situations.
Power On Preset (POR)
The ISL6185 POR feature inhibits device functionality when

(V/s). Resistive or active load slows the V ramp-up

toward the top of its curve.
Fault Blanking On Start-Up
During initial turn-on, the ISL6185 prevents nuisance faults from
being reported to the system controller by blanking the fault
signal until the internal FET is fully enhanced.
The ISL6185 also provides thermally insensitive timed OC turn-off
and fault notification. This isolates and protects the voltage bus in
the event of a peripheral OC event or short circuit event,
independent of the adjoining switch’s electrical or the ambient
thermal condition.
Current Trip and Limiting Levels
The ISL6185 undervoltage lockout feature prevents turn-on of
the outputs unless the correct ENABLE state and V > V
are present. During initial turn-on, the ISL6185 prevents fault
reporting by blanking the fault signal.
The ISL6185 provides integrated current sensing in the MOSFET
that allows for rapid control of OC events. Once an OC condition is
detected, the ISL6185 goes into its current limiting (CL) control
mode. The ISL6185 is variant specified to allow a continuous

During operation, once an OC condition is detected, the output
current increases past its continuous current rating, it will reach

is, the current trip level. The current trip level is in all cases

value slightly higher than the continuous current rating. The
speed of this current limiting control is inversely related to the
magnitude of the OC fault. Thus, a hard overcurrent is more

pass. If still in current limit after the current limit period has
elapsed, the output is turned off, and the fault is reported by
pulling the corresponding FAULT output low. On the latch-off
options, after turn-off, both the output and the FAULT signal are
latched low until reset by the enable signal being de-asserted or
until a POR occurs. At this time, the FAULT signal clears, and
the switch is ready to be turned back on. On the auto restart
options, the ISL6185 attempts to periodically turn on the
output, as long as the enable is asserted.

IN
When disabled, the ISL6185 has a low quiescent supply current
and an output-to-input reverse current flow blocking capability.
Over-Temperature Shutdown
Although the ISL6185 has an over-temperature shutdown and
lockout feature, because of the 12ms timed shutdown, the
thermal shutdown is likely to be invoked only in extremely high
ambient temperatures.
The ISL6185 family is provided with enable polarity options and
an industry-standard 8 lead SOIC pinout, along with two versions
in the 70% smaller 3x3 DFN. The 8 Ld DFN package offers the
same performance as the 8 Ld SOIC, whereas the 10 Ld DFN
offers higher current capability in the smallest possible package
because of lower package electrical and thermal resistance.
The over-temperature protection invokes and disables the switch
turn-on operation once the die temperature is ~+140°C. It turns
off an already on switch at ~+150°C and releases the part to
operation once the die temperature falls to ~+120°C.

ISL6185
Turn-off Time Delay
Latch-off Restart/Auto-Restart Start
During operation, once an OC condition is detected, the output
is current limited for ~12ms to allow transient OC conditions to
pass. If still in current limit and after the current limit period
has elapsed, the output is turned off, and the fault is reported
by pulling the corresponding FAULT low. The internal 12ms timer
starts upon current limiting and is independent of ambient or IC
thermal conditions, thus providing more consistent operation
over the entire temperature range.
After turn-off, with the latch-off options, both the output and the
FAULT signal are latched low until they are reset by the enable
signal being de-asserted. At this time, the FAULT signal clears,
and the IC is ready for enable to assert. On the auto restart
options, the ISL6185 attempts to periodically turn-on the
output at approximately 1s intervals, as long as the enable is
asserted. If the OC condition remains indefinitely, the fault
indication and the restart attempts also continue until the
thermal protection feature is invoked, thus increasing the
restart period.
Active Output Pull-down
Another ISL6185 feature is the 10kΩ active pull-down on the
outputs to <60mV above GND when the device is disabled, thus
ensuring discharge of the load.

Application Considerations
Application Information
Using the ISL6185xEVAL1Z Platform
General and Biasing Information
There are three evaluation platforms for the ISL6185 family.
There is one platform for each package style, each with a
different continuous output current level and a mix of enable
polarity and output retry or latch options. See page 4, at the end
of the “Ordering Information” table, for information on the
standard available evaluation board options. Figure 32A shows
the common schematic for all three evaluation boards. See “Pin
Configurations” on page 5 for details and differences.
The application considerations for the ISL6185 family are widely
accepted best industry practices. Good decoupling practices on
the VIN pin must be followed: placement close to the IC, with at
least 2.2µF recommended. It is recommended to reduce the
input and output inductance to the ISL6185 with good PCB
layout practices.
When designing with the 1.5A and 1.8A versions in an
implementation in which the output may be unloaded (open)
while the ISL6185 is turned on, a minimum of 4.7µF of
capacitive output load is recommended to prevent high dv/dt
from unnecessarily activating the surge/ESD control circuit.
The evaluation platform is biased and monitored through
numerous labeled test points. See Table 1 for test point
assignments and descriptions.
The ISL6185 provides several continuous current rated devices
specified at V = 5V; these are 0.6A, 1.1A, 1.5A and 1.8A
IN
options that are capable over the entire temperature extreme. At
V
= 3.3V, the current capability is degraded, and the ISL6185 is
IN
specified at 0.6A, 1.1A, 1.3A and 1.5A, respectively. At
= 2.5V, there are no minimum specifications, but a typical

External current loading in excess of the trip current level for the
particular part being evaluated will result in the ISL6185 entering
the current limiting mode. Figure 16 illustrates the current

continuous load current rating. The scope shot shows current
