Intersil ISL61851EVAL1Z Dual usb port power supply controller Datasheet

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
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.

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 allows
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 11 through 26 for typical
operational waveforms including both under and
overcurrent situations.
The ISL6185 offers current sense and limiting with
VIN = 5V guaranteed continuous current product
variants of 0.6A, 1.1A, 1.5A and 1.8A making these
devices well suited for a myriad of USB and other low
power (9W max) port power management applications
and configurations.
The ISL6185 also provides a thermally insensitive timed
OC turn-off and fault notification, isolating and protecting
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.
The ISL6185 undervoltage lockout feature prevents
turn-on of the outputs unless the correct ENABLE
state and VIN > VUVLO are present. During initial
turn-on the ISL6185 prevents fault reporting by
blanking the fault signal.
During operation, once an OC condition is detected
the output is current limited for tCL to allow transient
OC conditions to pass. If still in current limit after the
current limit period has elapsed, the output is then
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 a POR occurs at which time the
FAULT signal will clear and the switch is ready to be
turned back on. On the auto restart options the
ISL6185 will attempt to periodically turn-on the
output as long as the enable is asserted.
When disabled the ISL6185 has a low quiescent supply
current and output to input reverse current flow blocking
capability.
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.

Power On Preset (POR)
The ISL6185 POR feature inhibits device functionality
when VIN <VUVLO.
Reverse Polarity Protection
In any event where the power switch is disabled and
VOUT > VIN there will be no output to input current flow
nor will the output voltage appear on the input.
Soft-Start
Upon enable, the switch passes a constant current to
the load. The voltage on the VOUT pin will ramp up
according the equation: ILIM/COUT (V/s). Resistive or
active load will slow the VOUT ramp up toward the top
of its curve.
Fault Blanking On Start-Up
During initial turn-on, the ISL6185 prevents nuisance
faults being reported to the system controller by blanking
the fault signal until the internal FET is fully enhanced.
Current Trip and Limiting Levels
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 current (ICONT)
operation of 0.6A, 1.1A, 1.5A or 1.8A. As the current
increases past its continuous current rating it will reach a
level that causes the device to enter its current limit
mode, that is the current trip level. The current trip level
is in all cases adequately above the ICONT rating as to
not cause unintended false faults. The current limit is
specified at VOUT = VIN - 1V to test a known
representative condition and is featured at a nominal
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 quickly pulled to its limiting value
than a marginal OC condition.
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 only to be
invoked in extremely high ambient temperatures.
The over- temperature protection invokes and disables
the switch turn-on operation once the die temperature is
~+140°C, it will turn 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
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 then 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
providing more consistent operation over the entire
temp range.
Latchoff Restart/Auto-Restart Start
After turn-off, with the latch off options both the
output and the FAULT signal are latched low until
reset by the enable signal being de-asserted at which
time the FAULT signal will clear and the IC is ready for
enable to assert. On the auto restart options the
ISL6185 will attempt to periodically turn-on the
output at approximately 1s intervals as long as the
enable is asserted. If the OC condition remains
indefinitely so will the fault indication and the restart
attempts until such time that the thermal protection
feature is invoked 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 ensuring discharge of the load.

Application Information
Using the ISL6185xEVAL1Z Platform
General and Biasing Information
There are three (3) evaluation platforms for the ISL6185
family. There is one (1) 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 the
bottom of Table 1 for standard available evaluation board
options. Figure 30A, illustrates the common schematic
for all of the evaluation boards, consult the individual
package pinouts for those differences.
The evaluation platform is biased and monitored through
numerous labeled test points. See Table 1 for test point
assignments and descriptions.

Upon proper bias and of the evaluation platform and
correct enabling of the IC the ISL6185 will have a
nominal VIN/10Ω load current passing through each
enabled switch which is below the continuous current
rating. See Figures 11 and 12 for typical ISL6185 turn-on
and off waveforms.
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 14
illustrates the current limiting mode for the ISL6185
product variants with 0.6A of continuous load current
rating. The scope shot shows current limiting for ~12ms
before it is turned off and the fault signal is asserted.

Application Considerations
The application considerations for the ISL6185 family are
widely accepted best industry practices. Good decoupling
practices on the VIN pin must be followed with placement
close to the IC with at least 2.2µF being recommended.
Work 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 where 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 ISL6185 provides several continuous current rated
devices specified at VIN = 5V, these are 0.6A, 1.1A, 1.5A
and 1.8A options capable over the entire temperature
extreme. At VIN = 3.3V the current capability is
degraded and the ISL6185 is specified at 0.6A, 1.1A,
1.3A and 1.5A respectively. At VIN = 2.5V there are no
min specifications but a typical value is provided for
+25°C operation in the specification table. This degraded
capability is due to the higher rDS(ON) of the FET switch
at the lower bias voltage.
The enhanced thermal characteristics and increased
number of bond wires allows the 10 Ld DFN to have a
higher current capability than either the 8 Ld SOIC or
DFN.
