AP2401/AP2411
2.0A SINGLE CHANNEL CURRENT-LIMITED
POWER SWITCH WITH LATCH-OFF
Description
The AP2401 and AP2411 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. AP2401 and AP2411 will be
latched off after 7ms deglitch.
All devices are available in SO-8, MSOP-8, MSOP-8EP,
U-DFN3030-8 and U-DFN2020-6 packages.

Application Information
Power Supply Considerations
A 0.1F to 2.2F 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 2.2F 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 0.1F to 1.0F 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 devices will limit the current until the overload condition is removed
or the internal deglitch time (7-ms typical) is reached and the device is turned off. The device will remain latched off even overload condition is
removed until power is cycled or the device enable is toggled.
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 AP2401/AP2411 senses the short circuit and immediately clamps output current to a certain safe level namely ILIMIT,
and turns off after deglitch time(7-ms typical).
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 current for deglitch time period
(7-ms typical), and then turned off.
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 AP2401/AP2411 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 output current is clamped at ILIMIT for deglitch time period (7-ms typical), and then turned off.
FLG Response
When an over-current or over-temperature shutdown condition is encountered, the FLG open-drain output goes active low after a nominal 7-ms
deglitch timeout.
When that happens, the FLG will remain low and the switch will be latched off until the fault condition is 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 AP2401/AP2411 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 RJA + TA
Where:
TA= Ambient temperature°C
RJA = 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
AP2401/AP2411 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 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 occurs with 7-ms deglitch.
When the FLG is asserted, the switch will be latched off until the temperature drops to 20°C below the thermal shutdown threshold and the power
or EN pin is cycled.

Application Information (cont.)
Under-Voltage Lockout (UVLO)
Under-voltage 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.
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.
