AP2501A/AP2511A
2.0A SINGLE CHANNEL CURRENT-LIMITED POWER SWITCH
Description
The AP2501A and AP2511A are single channel, current-limited,
integrated, high-side power switches optimized for Universal Serial
Bus (USB) and other hot-swap applications. This 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, and 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 and U-DFN2020-6 packages.

AP2501A/AP2511A
Application Information (continued)
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
AP2501A/AP2511A 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 AP2501A/AP2511A is ramped
to its operating voltage prior to enabling the output. Since the AP2501A/AP2511A 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 AP2501A/AP2511A is disabled. An overstress condition to the device's discharge MOS transistor may result.
