The AP2181D and AP2191D are integrated high-side power
switches optimized for Universal Serial Bus (USB) and other
hot-swap applications. The family of devices complies with
USB 2.0 and available with both polarities of Enable input.
They offer current and thermal limiting 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.
Applications

... Application Note The AP2181D and AP2191D are integrated high-side power switches optimized for Universal Serial Bus (USB) that requires protection functions. The power switches are equipped with a driver that controls the gate voltage and incorporates slew-rate limitation. This, along with the various protection features and special functions, makes these power switches ideal for hot-swap or hot-plug applications ...

Page 10

... Thermal protection prevents the IC from damage when the die temperature exceeds safe margins. This mainly occurs when heavy-overload or short-circuit faults are present for extended periods of time. The AP2181D/AP2191D implements a thermal sensing to monitor the operating junction temperature of the power distribution switch. Once the die temperature rises to approximately 140°C, the Thermal protection feature gets activated as follows: The internal thermal sense circuitry turns the power switch off and the FLG output is asserted thus preventing the power switch from damage ...

Page 11

... Due to the controlled rise times and fall times of the AP2181D/AP2191D, these devices can be used to provide a softer start-up to devices being hot-plugged into a powered system. The UVLO feature of the AP2181D/AP2191D also ensures that the switch is off after the card has been removed, and that the switch is off during the next insertion ...
