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 (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.
