0.5 SINGLE CHANNEL CURRENT-LIMITED
POWER SWITCH WITH OUTPUT DISC HA RGE
Description
The AP2141D and AP2151D 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.
All devices are available in SOT25, SO-8, MSOP-8EP, and
U-DFN2018-6 packages.

AP2141D/ AP2151D
Application Information
The AP2141D and AP2151D 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-rat e limitation. This, along with the various protection
features and special functions, makes these power switches ideal for hot-swap or hot-plug applications.
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 1.9V, the power switch is turned off. This facilitates the design of hot-insertion systems where it is n ot 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 overcurrent 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.
The different overload conditions and the corresponding response of the AP2141D/2151D are outlined below:
S.NO Conditions Explanation Behavior of the AP2141D/2151D
1 Short circuit condition at start-up Output is shorted before input
voltage is applied or before the
part is enabled
The IC senses the short circuit and immediately clamps output
current to a certain safe level namely ILIMIT.
2 Short-circuit or Overcurrent
condition
Short-Circuit or Overload 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.
3 Gradual increase from nominal
operating current to ILIMIT Load increases gradually until the
current-limit threshold.(ITRIG)
The current rises until ITRIG or thermal limit. Once the threshold
has been reached, the device switches into its current limiting
mode and is set at ILIMIT.
Note that when the output has been shorted to GND at extremely low temperature (< -20oC), a minimum 120 F electrol ytic 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.
Thermal Protection
Thermal protection prevents the IC from damage when the die tem peratur e e xceeds safe margins. This mainly occurs when heav y-o ve rload or short -
circuit faults are present for extended periods of time. The AP2141D/AP2151D 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 circ uit allows the device to cool down to a pproximately 25°C befo re 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.
Reverse Current Pro t ectio n
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 out put voltage and the input voltage. When the s witch is disabled, this feature blocks
reverse current flow from the output back to the input.

Application Information (cont.)
Special Functions:
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 100. 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.
FLG Response
The FLG open-drain output goes active low for an y of the t wo conditions: Over-Cur rent or Ove r-Tem perature. 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-tempera ture conditions
are removed. Connecting a heavy capac itive 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
AP2141D/AP2151D are designed to eliminate erroneous Over-current reporting without the need for external components, such as an RC delay
network.
Power Supply Considerations
A 0.01-F to 0.1-F X7R or X5R ceramic b ypass 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-F minimum) and output pin(s) is recommended when the
output load is heavy. This precaution also reduces power-supply transients that may cause ringing on the input. Additionally, bypassing the output
with a 0.01-F to 0.1-F ceramic capacitor improves the immunity of the device to short-circuit transients. This capacitor also prevents the output
from going negative during turn-off due to inductive parasitics.
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:
PD = RDS(ON)× I2
The junction temperature can be calculated by:
TJ = PD x RJA + TA
Where:
TA= Ambient temperature °C
RJA = Thermal resistance
PD = Total power dissipation
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 AP2141D/AP2151D, these devices can be used to provide a softer
start-up to devices being hot-plugged into a powered s ystem. The UVLO feature of the AP2141D/AP2151D also e nsures that the switch is off after
the card has been removed, and that the switch is off during the next insertion.
By placing the AP2141D/AP2151D 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.
