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.

6, 7 5 Voltage Output Pin (all OUT pins must be tied together externally)
8 6 No Internal Connection. Recommend tie to OUT pins.
Exposed Pad
Exposed pad. It should be externally connected to GND plane and thermal mass for
Exposed Pad enhanced thermal impedance. Exposed pad should not be used as electrical ground
conduction path.

5. UL Recognized Rating from -30°C to +70°C (Diodes qualified TST from -65°C to +150°C).
Caution: Stresses greater than the 'Absolute Maximum Ratings' specified above, may cause permanent damage to the device. These are stress ratings
only; functional operation of the device at these or any other conditions exceeding those indicated in this specification is not implied. Device reliability may
be affected by exposure to absolute maximum rating conditions for extended periods of time.
Semiconductor devices are ESD sensitive and may be damaged by exposure to ESD events. Suitable ESD precautions should be taken when handling
and transporting these devices.
