AP2501/AP2511
2.5A SINGLE CHANNEL CURRENT-LIMITED POWER SWITCH
Description
The AP2501 and AP2511 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 and
U-DFN3030-8 Type E packages.

Application Note (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.
