General Description
The AAT4626 SmartSwitch is part of Skyworks' Application
Specific Power MOSFET (ASPM™) product family. It is a
dual-channel 500mA current-limited P-channel MOSFET
power switch designed for high-side load switching appli-
cations. This switch operates with inputs ranging from
2.7V to 5.5V, making it ideal for both
3V and 5V systems. An integrated current-limiting circuit
protects the input supply against large changes in load
current which may cause the supply to fall out of regula-
tion. The AAT4626 is also protected from thermal over-
load which limits power dissipation and junction tem-
peratures. The current limit threshold is factory pro-
grammed at 1.0A, with a maximum of 1.5A. The quies-
cent supply current is typically a low 20µA. In shutdown
mode, the supply current decreases to less than 1µA.
The AAT4626 is available in a Pb-free, 8-pin SOP pack-
age and is specified over the -40°C to +85°C tempera-
ture range.
The AAT4600 series is a family of adjustable and fixed
SmartSwitch products with a range of current handling
capabilities. Single versions are available with adjustable
current limit (AAT4601) or fixed current limit (AAT4626),
as well as dual versions with fixed current limit (AAT4626).

Functional Description
The AAT4626 is a dual integrated MOSFET load switch
with a fixed level current limit, over-temperature protec-
tion, level shifted inputs, and a fault flag for each switch.
The current limit control is combined with an over-tem-
perature thermal limit circuit to provide a comprehen-
sive system to protect the load switch under short-circuit
or other adverse operating conditions. The AAT4626 is
ide- ally suited for control and protection of peripheral
ports such as USB, RS232, and parallel ports.
The current limit and over-temperature circuits will act
independently. The device current limit is activated when
the output load current exceeds a preset internal thresh-
old level. The minimum current limit threshold charac-
ter- istic is specified by ILIM(MIN). If the load switch ambi-
ent temperature becomes excessive or if a short-circuit
con- dition persists, the die temperature will rise, caus-
ing the over-temperature protection circuit to activate.
If the current limit or over-temperature protection cir-
cuits are active for more than ten milliseconds, the sys-
tem will be informed via the FAULT flag. The ten millisec-
ond fault blanking delay allows the AAT4626 to be
turned on into large capacitive loads without activating
the FAULT flags. The open drain FAULT outputs can be
con- nected directly to system controllers driven by volt-
age levels less than the IN pin voltage without addi-
tional level shifting circuitry.
Each of the two load switches is turned on and off by
applying a logic level signal to the EN(A/B) pin. The
AAT4626 enable function is available in both active high
and active low logic level versions. The AAT4626 typi-
cally consumes 20µA when operating; when off, the
device draws less than 1µA. In the off state, current is
prevented from flowing between the input and output on
each respective channel. The EN(A/B) function has logic
level thresholds that allow the AAT4626 to be TTL com-
patible and may also be controlled by 2.5V to 5.0V
CMOS circuits. The voltage level on either EN(A/B) or
FAULT(A/B) should not exceed the input supply level
present on the IN pin.

Applications Information
Operation in Current Limit
If an excessive load is applied to either output of an
AAT4626, the load current will be limited by the device’s
current limit circuitry. Refer to the “Current Limit” curve
in the Typical Characteristics section of this datasheet. If
a short circuit were to occur on the load applied to either
the A or B output, there would be a demand for more cur-
rent than what is allowed by the internal current limiting
circuit and the voltage at the device output will drop. This
causes the AAT4626 to dissipate more power than in nor-
mal operation, causing the die temperature to increase.
When die temperature exceeds the internal over-temper-
ature threshold, the AAT4626 will shut down both the A
and B output channels. After shutting down, the AAT4626
cools to a level below the over-temperature threshold, at
which point it will start up again. The AAT4626 will con-
tinue to cycle off and on until one of the following events
occurs: the load current is reduced to a level below the
AAT4626’s current limit setting; the input power is
removed; or the output is turned off by a logic high level
applied to the EN pin.
Thermal Considerations
Since the AAT4626 has internal current limit and over-
temperature protection, junction temperature is rarely a
concern. If an application requires a large load current in
a high temperature operating environment, there is the
possibility that the over-temperature protection circuit
rather than the current limit circuit from one of the two
outputs will regulate the current available to the load. In
these applications, the maximum current available with-
out risk of activation of the over-temperature circuit can
be calculated. The maximum internal temperature while
current limit is not active can be calculated using
Equation 1:
TJ(MAX) = IMAX
2 ∙ RDS(ON)(MAX) ∙ RθJA + TA(MAX)
In Equation 1, IMAX is the maximum current required by
the load. RDS(ON)(MAX) is the maximum rated RDS(ON) of the
AAT4626 at high temperature. RqJA is the thermal resis-
tance between the device die and the board onto which it
is mounted. TA(MAX) is the maximum ambient temperature
for the printed circuit board assembly under the AAT4626
when the load switch is not dissipating power. Equation 1
can be transformed to provide IMAX; Refer to Equation 2.
=
IMAX
TSD(MIN) - TA(MAX)
RDS(ON)(MAX) RθJA
TSD(MIN) is the minimum temperature required to activate
the device over-temperature protection. The typical
thermal limit temperature specification is 125°C for the
AAT4626; for calculations, 115°C is a safe minimum
value to use.
For example, a portable device is specified to operate in
a 50°C environment. The printed circuit board assembly
will operate at temperatures as high as 85°C. This por-
table device has a sealed case and the area of the
printed board assembly is relatively small, causing RqJA to
be approximately 100°C/W. RDS(ON)(MAX) = 130mΩ. Using
Equation 2,
=
IMAX = 1.52A
115°C - 85°C
0.13Ω · 100°C/W
If this system requires less than 1.52A, the thermal limit
will not activate during normal operation.
Input Capacitor
The input capacitor serves two purposes. First, it pro-
tects the source power supply from transient current
effects generated by the application load circuit. If a
short circuit is suddenly applied to the output of an
AAT4626, there is a microsecond long period during
which a large current can flow before the current limit
circuit becomes active. Refer to the characteristic curve
“Short Circuit Through 0.3W." A properly sized input
capacitor can dramatically reduce the load switch input
transient response effects seen by the power supply and
other circuitry upstream from the AAT4626.
The second purpose of the input capacitor is to prevent
transient events generated by the load circuits from
effecting the operation of the AAT4626. For example, if
an AAT4626 is used in a circuit that operates from a 5V
power supply with poor step load response, it is possible
that turning on the load switch could cause the input
power supply to droop below the AAT4626's under-volt-
age lockout threshold. This drop in voltage would cause
the AAT4626 to turn off until the input power supply
voltage levels recover. Since this cycle would be self-
perpetuating, the entire circuit could be seen to be
unstable. In the very rare case where capacitor cost is
prohibitive and the input capacitor is omitted, the output
load circuit should be slew rate limited when turned on.

Output Capacitor
In order to insure stability while the device current limit
is active, a small capacitance of approximately 1µF
should be used on each output. When either output of
the AAT4626 is activated using the EN(A/B) function,
there are no momentary current transients, as in the
case when a short circuit is suddenly applied to a device
that is already on. Refer to the Typical Characteristics
curve “Turn-On/Off Response.” Regardless of output
capacitor size, output current on either output is limited
to the value allowed by the threshold determined by the
internal current limiting circuitry. Refer to the internal
current limit threshold specifications stated in the
Electrical Characteristics section of this datasheet. This
permits very large output capacitors to be used.
For example, USB ports are specified to have at least
120µF of downstream capacitance from their controlling
power switch. An output capacitance as large as 1000µF
would not disturb the input power supply to an AAT4626
used to control a USB port.
EN Input
The AAT4626 has two enable inputs, ENA and ENB. These
two enable inputs allow the AAT4626 to independently
control each respective output. The device is available in
both active high EN enable and active low (EN) enable
versions. For specific part numbers, refer to the ordering
information section. When both the A and B outputs of
the AAT4626 are in the off state, the respective outputs
are an open circuit and the device quiescent current con-
sumption is reduced to less than 1µA. The ENA and ENB
threshold voltages are set to allow the AAT4626 to be
controlled by 5V TTL levels, as well as CMOS-compatible
levels ranging from 2.5V to 5V. The ENA or ENB function
control voltage levels should not exceed the input supply
level applied to the IN pin.
Fault Flag Output
The AAT4626 features an active low fault flag (FLGA and-
FLGB) output for each A and B output channel. The fault-
flags are provided to alert the system if the over-curren-
tor over-temperature circuits become active, or if the
load switch is not receiving a sufficient voltage level to
properly operate. If either the current limit or overtem-
perature circuits in any combination are constantly active
for more than approximately ten milliseconds, the
FLG(A/B) pin is pulled to ground internally through an
open drain device. The 10ms delay on the fault function
is intended to prevent capacitive loads connected to one
of the load switch outputs from activating its respective
flag when the device is turned on. The placement of a
pull-up resistor between the FLGA or FLGB pin and the IN
pin is recommended. Reasonable values for the pullup
resistor should range from 10kW to 100kW. Since the
fault flags are open drain terminals, they may be pulled
up to any voltage that is not greater than the level pres-
ent on the IN pin. This is done to allow the AAT4626 to
signal ancillary circuitry that is powered by voltage levels
less than the level on the IN pin.
If a fault flag delay greater than 10ms is required, addi-
tion delay may be added by use of an RC filter. As shown
in Figure 1, an RC filter can be added to the fault flag
output.

Reverse Voltage
The AAT4626 is designed to control current flowing from
IN to OUT. If a voltage is applied to OUT which is great-
er than that on IN, a large resulting reverse current may
flow, potentially damaging the AAT4626.
Under-Voltage Lockout
The AAT4626 has been designed with an under-voltage
lockout control circuit. The under-voltage lockout pre-
vents the output MOSFET devices from turning on until
VIN exceeds the typical UVLO threshold of 2.3V. During
operation, the device will automatically shut down if VIN
falls below the UVLO threshold and the fault flags will be
toggled.

Hot-Plug Applications
Application circuit cards with a high inrush current poten-
tial can be limited by use of the AAT4626. The AAT4626
has both slew rate limited turn on characteristics and cur-
rent limit controlled outputs, which make it ideally suited
for power port hot-plug applications. A host power back
plane or hot-plug receptacle may be sensitive to short
duration, high power surges. The AAT4626 will turn on in
a linear ramping fashion and regulate the inrush current
within the specified current limit for the device. The error
flag usually will not be affected during application turn-on
since the 10ms fault flag blanking time is intended for
these types of events. If an application turn-on current
surge exceeds 10ms, an RC delay filter may be added to
the flag output to prevent the system from receiving an
error during the start-up sequence.
PCB Layout Information
In order to obtain the maximum performance from the
AAT4626, very careful attention must be considered in
regard to the printed circuit board layout. In most port
power switch and port protection applications, high volt-
age and current transient events will occur. Proper PCB
layout can help reduce the effects of transient events.
PCB trace resistance will effect overall circuit transient
response; small voltage drops will also be incurred.
Refer to the following guidelines for power port PCB lay-
out:
1. PCB traces should be kept as short and direct as pos-
sible to minimize the effects of the PCB on circuit
performance.
2. Make component solder pads large to minimize con-
tact resistance.
3. The AAT4626 output bulk capacitors and ferrite
beads should be placed as close to the device as pos-
sible. PCB traces to the output connector should be
kept as short as possible to minimized trace resis-
tance and the associated voltage drop (I2R loss).
4. If ferrite beads are used in the circuit, select ferrite
beads with a minimum series resistance.
5. The use of PCB trace vias should be avoided on all
traces that conduct high currents. If vias are neces-
sary, make the vias as large as possible and use
multiple vias connected in parallel to minimize their
effect.
Evaluation Board Layout
The AAT4626 evaluation layout follows the recommend
printed circuit board layout procedures and can be used
as an example for good application layouts. (See Figures
4, 5, and 6.) Note that ferrite beads are not used on this
simple device evaluation board. The board layout shown
is not to scale.
