2.0A SINGLE CHANNEL CURRENT-LIMITED
POWER SWITCH WITH LATCH-OFF
Description
The AP2401A and AP2411A 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, overcurrent, over-temperature 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 overcurrent reporting and does
not require any external components. AP2401A and AP2411A will be
latched off after a 7ms deglitch.
All devices are available in SO-8, MSOP-8, MSOP-8EP,
U-DFN3030-8 and U-DFN2020-6 packages.

Application Information (continued)
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.
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
AP2401A/AP2411A 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
AP2401A/AP2411A is ramped to its operating voltage prior to enabling the output. Since the AP2401A/AP2411A 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 AP2401A/AP2411A is disabled. An overstress condition to the device's discharge MOS transistor may result.
