AP2161D/AP2171D
1A SINGLE CHANNEL CURRENT-LIMITED POWER
SWITCH WITH OUTPUT DISCHARGE
Description
Pin Assignments
The AP2161D and AP2171D are integrated high-side power
switches optimized for Universal Serial Bus (USB) and other
hot-swap applications. The family of devices complies with
USB 2.0 and is available with both polarities of Enable input.
They offer current and thermal limiting and short circuit
protection as well as controlled rise time and under-voltage
lockout functionality. A 7ms deglitch capability on the open-
drain Flag output prevents false over-current reporting and
does not require any external components.

AP2161D/AP2171D
1A SINGLE CHANNEL CURRENT-LIMITED POWER
SWITCH WITH OUTPUT DISCHARGE
Application Note
The AP2161D and AP2171D are integrated high-side
power switches optimized for Universal Serial Bus (USB)
that require protection functions. The power switches are
equipped with a driver that controls the gate voltage and
incorporates slew-rate limitation. This, along with the
various protection features and special functions, makes
these power switches ideal for hot-swap or hot-plug
applications.
1.9V, the power switch is turned off. This facilitates the
design of hot-insertion systems where it is not possible to
turn off the power switch before input power is removed.
Over-current and Short Circuit Protection
An internal sensing FET is employed to check for over-
current conditions. Unlike current-sense resistors, sense
FETs do not increase the series resistance of the current
path. When an over-current condition is detected, the
device maintains a constant output current and reduces
the output voltage accordingly. Complete shutdown
occurs only if the fault stays long enough to activate
thermal limiting.
Protection Features:
Under-voltage Lockout (UVLO)
Under-voltage lockout function (UVLO) guarantees that
the internal power switch is initially off during start-up.
The UVLO functions only when the switch is enabled.
Even if the switch is enabled, the switch is not turned ON
until the power supply has reached at least 1.9V.
Whenever the input voltage falls below approximately
The different overload conditions and the corresponding
response of the AP2161D/2171D are outlined below:

Explanation
Behavior of the AP2161D/2171D

condition that occurs when
the part is enabled.
• At the instance the overload occurs, higher current
may flow for a very short period of time before the
current limit function can react.
• After the current limit function has tripped (reached
the over-current trip threshold), the device
switches into current limiting mode and the current
is clamped at ILIMIT
.

threshold has been reached, the device switches into
its current limiting mode and is set at ILIMIT.
threshold.(ITRIG
)
Note that when the output has been shorted to GND at
extremely low temperature (< -30oC), a minimum 120-μF
electrolytic capacitor on the output pin is recommended. A
correct capacitor type with capacitor voltage rating and
temperature characteristics must be properly chosen so
that capacitance value does not drop too low at the
extremely low temperature operation. A recommended
capacitor should have temperature characteristics of less
than 10% variation of capacitance change when operated
at extremely low temp. Our recommended aluminum
electrolytic capacitor type is Panasonic FC series.
present for extended periods of time. The
AP2161D/AP2171D implements thermal sensing to
monitor the operating junction temperature of the power
distribution switch. Once the die temperature rises to
approximately 140°C, the Thermal protection feature gets
activated as follows: The internal thermal sense circuitry
turns the power switch off and the FLG output is asserted
thus preventing the power switch from damage.
Hysteresis in the thermal sense circuit allows the device
to cool down to approximately 25°C before the output is
turned back on. The built-in thermal hysteresis feature
avoids undesirable oscillations of the thermal protection
circuit. The switch continues to cycle in this manner until
the load fault is removed, resulting in a pulsed output.
The FLG open-drain output is asserted when an over-
current occurs with 7-ms deglitch.
Thermal Protection
Thermal protection prevents the IC from damage when
the die temperature exceeds safe margins. This mainly
occurs when heavy-overload or short-circuit faults are

SWITCH WITH OUTPUT DISCHARGE
Application Note (Continued)
Reverse Current Protection
may cause ringing on the input. Additionally, bypassing
the output with a 0.01-μF to 0.1-μF ceramic capacitor
improves the immunity of the device to short-circuit
transients. This capacitor also prevents output from going
negative during turn-off due to inductive parasitics.
In a normal MOSFET switch, current can flow in reverse
direction (from the output side to the input side) when the
output side voltage is higher than the input side, even
when the switch is turned off. A reverse-current blocking
feature is implemented in the AP21x1 series to prevent
such back currents. This circuit is activated by the
difference between the output voltage and the input
voltage. When the switch is disabled, this feature blocks
reverse current flow from the output back to the input.
Power Dissipation and Junction Temperature
The low on-resistance of the internal MOSFET allows the
small surface-mount packages to pass large current.
Using the maximum operating ambient temperature (TA)
and RDS(ON), the power dissipation can be calculated by:
Special Functions:
PD = RDS(ON)× I2
Discharge Function
When enable is de-asserted, the discharge function is
active. The output capacitor is discharged through an
internal NMOS that has a discharge resistance of 100ꢀ.
Hence, the output voltage drops down to zero. The time
taken for discharge is dependent on the RC time constant
of the resistance and the output capacitor.
The junction temperature can be calculated by
TJ = PD x RθJA + TA
Where:
TA= Ambient temperature °C
RθJA = Thermal resistance
PD = Total power dissipation
FLG Response
The FLG open-drain output goes active low for any of the
two conditions: Over-Current or Over-Temperature. The
time from when a fault condition is encountered to when
the FLG output goes low is 7-ms (TYP). The FLG output
remains low until both over-current and over-temperature
conditions are removed. Connecting a heavy capacitive
load to the output of the device can cause a momentary
Over-current condition, which does not trigger the
FLG due to the 7-ms deglitch timeout. The 7-ms timeout is
also applicable for Over-current recovery and Thermal
recovery. The AP2161D/AP2171D are designed to
eliminate erroneous Over-current reporting without the
need for external components, such as an RC delay
network.
Generic Hot-Plug Applications
In many applications it may be necessary to remove
modules or PC boards while the main unit is still
operating. These are considered hot-plug applications.
Such implementations require the control of current
surges as seen by the main power supply and the card
being inserted. The most effective way to control these
surges is to limit and slowly ramp up the current and
voltage being applied to the card, similar to the way in
which a power supply normally turns on. Due to the
controlled rise and fall times of the AP2161D/AP2171D,
these devices can be used to provide a softer start-up to
devices being hot-plugged into a powered system. The
UVLO feature of the AP2161D/AP2171D also ensures
that the switch is off after the card has been removed,
and that the switch is off during the next insertion.
Applications Information:
Power Supply Considerations
A 0.01-μF to 0.1-μF X7R or X5R ceramic bypass
capacitor between IN and GND, close to the device, is
recommended. This limits the input voltage drop during
line transients. Placing a high-value electrolytic capacitor
on the input (10-μF minimum) and output pin(s) is
recommended when the output load is heavy. This
precaution also reduces power-supply transients that
By placing the AP2161D/AP2171D between the VCC input
and the rest of the circuitry, the input power reaches
these devices first after insertion. The typical rise time of
the switch is approximately 1ms, providing a slow voltage
ramp at the output of the device. This implementation
controls the system surge current and provides a
hot-plugging mechanism for any device.
