0.5A SINGLE CHANNEL CURRENT-LIMITED POWER SWITCH
Description
The AP2141 and AP2151 are integrated high-side power switches
optimized for Universal Serial Bus (USB) and other hot-swap
applications. This 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 undervoltage 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 SO-8, MSOP-8EP, SOT25 and U-
DFN2018-6 packages.

Application Information
Power Supply Considerations
A 0.01μF to 0.1μF X7R or X5R ceramic bypass capacitor between IN and GND, close to the device, is recommended. Placing a high-value
electrolytic capacitor on the input (10μF minimum) and output pin(s) is recommended when the output load is heavy. This precaution reduces
power-supply transients that may cause ringing on the input. Additionally, bypassing the output with a 0.01μF to 0.1μF ceramic capacitor improves
the immunity of the device to short-circuit transients.
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.
Three possible overload conditions can occur. In the first condition, the output has been shorted to GND before the device is enabled or before VIN
has been applied. The AP2141/AP2151 senses the short circuit and immediately clamps output current to a certain safe level namely ISHORT.
In the second condition, an output short or an overload occurs while the device 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.
In the third condition, the load has been gradually increased beyond the recommended operating current. The current is permitted to rise until the
current-limit threshold (ITRIG) is reached or until the thermal limit of the device is exceeded. The AP2141/AP2151 is capable of delivering current
up to the current-limit threshold without damaging the device. 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 (< -30°C), a minimum 120μF 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.
FLG Response
When an over-current or over-temperature shutdown condition is encountered, the FLG open-drain output goes active low after a nominal 7ms
deglitch timeout. 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 7ms deglitch
timeout. The FLG will be triggered at above 500mA to indicate possible Over-Current condition. The AP2141/AP2151 is designed to eliminate
false over-current reporting without the need of external components to remove unwanted pulses.
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
Finally, calculate the junction temperature:
TJ = PD x RθJA + TA
Where:
TA = Ambient temperature °C
RθJA = Thermal resistance
PD = Total power dissipation

AP2141/ AP2151
Application Information (Cont.)
Thermal Protection
Thermal protection prevents the IC from damage when heavy-overload or short-circuit faults are present for extended periods of time. The
AP2141/AP2151 implements a thermal sensing to monitor the operating junction temperature of the power distribution switch. Once the die
temperature rises to approximately +140°C due to excessive power dissipation in an over-current or short-circuit condition, the internal thermal
sense circuitry turns the power switch off, thus preventing the power switch from damage. Hysteresis is built into the thermal sense circuit allowing
the device to cool down approximately +25°C before the switch turns back on. The switch continues to cycle in this manner until the load fault or
input power is removed. The FLG open-drain output is asserted when an over-temperature shutdown or over-current occurs with 7ms deglitch.
Under-Voltage Lockout (UVLO)
Undervoltage lockout function (UVLO) keeps the internal power switch from being turned on until the power supply has reached at least 1.9V,
even if the switch is enabled. Whenever the input voltage falls below approximately 1.9V, the power switch is quickly 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.
Host/Self-Powered HUBs
Hosts and self-powered hubs (SPH) have a local power supply that powers the embedded functions and the downstream ports (see Figure 2).
This power supply must provide from 5.25V to 4.75V to the board side of the downstream connection under both full-load and no-load conditions.
Hosts and SPHs are required to have current-limit protection and must report over-current conditions to the USB controller. Typical SPHs are
desktop PCs, monitors, printers, and stand-alone hubs.
Figure 2. Typical One-Port USB Host / Self-Powered Hub
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 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 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 AP2141/AP2151, 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 AP2141/AP2151 also ensures that the switch is off after
the card has been removed, and that the switch is off during the next insertion.
By placing the AP2141/AP2151 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 system
surge current and provides a hot-plugging mechanism for any device.
Dual-Purpose Port Applications
AP2141/AP2151 is not recommended for use in dual-purpose port applications in which a single port is used for data communication between the
host and peripheral devices while simultaneously maintaining a charge to the battery of the peripheral device. An example of such a non-
recommended application is a shared HDMI/MHL (Mobile High-definition Link) port that allows streaming video between an HDTV or set-top box
and a smartphone or tablet while maintaining a charge to the smartphone or tablet battery. If a voltage is maintained across the output of the
AP2141/AP2151 when the output is disabled and the VIN of the device is subsequently ramped up, an overstress condition to the AP2141/AP2151
may result.
