AP2301A/AP2311A
2.0A SINGLE CHANNEL CURRENT-LIMITED POWER SWITCH
Description
The AP2301A and AP2311A are single channel, current-limited,
integrated high-side power switches optimized for Universal Serial
Bus (USB) and other hot-swap applications. The family of devices
complies with USB standards and is available with both polarities of
Enable input.
The devices have fast short-circuit response time for improved overall
system robustness, and have integrated output discharge function to
ensure completely controlled discharging of the output voltage
capacitor. They provide a complete protection solution for applications
subject to heavy capacitive loads and the prospect of short circuit,
and offer reverse current blocking, over-current, over-temperature
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 SO-8, MSOP-8, MSOP-8EP, U-DFN3030-
8 (Type E) and U-DFN2020-6 packages.

Application Information
Power Supply Considerations
A 0.1μF to 2.2μF X7R or X5R ceramic bypass capacitor placed between IN and GND, close to the device, is recommended. When an external
power supply is used, or an additional ferrite bead is added to the input, high inrush current may cause voltage spikes higher than the device
maximum input rating during short circuit condition. In this case a 2.2μF, or bigger capacitor is recommended. Placing a high-value electrolytic
capacitor on the input 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 0.1μF to 1.0μF 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 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.
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 AP2301A/AP2311A senses the short circuit and immediately clamps output current to a certain safe level, namely ILIMIT.
In the second condition, an output short or an overload occurs while the device is enabled. At the instance the overload occurs, higher inrush
current may flow for a very short period of time before the current limit function can react. The input capacitor(s) rapidly discharge through the
device, activating current limit circuitry. Protection is achieved by momentarily opening the P-MOS high-side power switch and then gradually
turning it on. 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 AP2301A/AP2311A 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.
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 AP2301A/AP2311A 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
Thermal Protection
Thermal protection prevents the IC from damage when heavy-overload or short-circuit faults are present for extended periods of time. The
AP2301A/AP2311A 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 +20°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.
Undervoltage Lockout (UVLO)
Undervoltage lockout function (UVLO) keeps the internal power switch from being turned on until the power supply has reached at least 2V, even
if the switch is enabled. Whenever the input voltage falls below approximately 2V, 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.

AP2301A/AP2311A
Application Information (Cont.)
Discharge Function
The discharge function of the device is active when enable is disabled or de-asserted. The discharge function with the N-MOS power switch
implementation is activated and offers a resistive discharge path for the external storage capacitor. This is designed for discharging any residue of
the output voltage when either no external output resistance or load resistance is present at the output.
Dual-Purpose Port Applications
AP2301A/AP2311A is suitable 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 this 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. In such dual-purpose port applications, it is important to insure VIN of the
AP2301A/AP2311A is ramped to its operating voltage prior to enabling the output. Since the AP2301A/AP2311A includes an embedded discharge
feature that discharges the output load of the device when the device is disabled, the batteries of the connected peripheral device will be subject to
continual discharge whenever the AP2301A/AP311A is disabled. An overstress condition to the device's discharge MOS transistor may result.
