AP2301A/AP2311A
2.0A SINGLE CHANNEL CURRENT-LIMITED POWER SWITCH
Description
The AP2301A and AP2311A 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, U-DFN3030-
8 and U-DFN2020-6 packages.

Voltage Input Pin; Connect a 0.1µF or larger ceramic capacitor from IN to GND as close
as possible. (all IN pins must be tied together externally)
Enable input, active low (AP2301A) or active high (AP2311A)
Over-temperature and over-current fault reporting with 7ms deglitch; active low open-
drain output. FLG is disabled for 7ms after turn-on.
Voltage Output Pin All OUT pins must be tied together externally.
NC:
No Internal Connection; recommend tie to OUT pins
Exposed pad.
It should be externally connected to GND and thermal mass for enhanced thermal
impedance. It should not be used as electrical ground conduction path.
