Description
The AP2166 and AP2176 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.
All devices are available in SOP-8L and MSOP-8L-EP packages.

... Complete shutdown occurs only if the fault stays long enough to activate thermal limiting. Three possible overload conditions can occur. In the first condition, the output has been shorted to GND before the device is enabled or before VIN has been applied. The AP2166/AP2176 senses the short circuit and immediately clamps output current to a certain safe level namely I In the second condition, an output short or an overload occurs while the device is enabled ...

... Thermal Protection Thermal protection prevents the IC from damage when heavy-overload or short-circuit faults are present for extended periods of time. The AP2166/AP2176 implements a thermal sensing to monitor the operating junction temperature of the power distribution switch. Once the die temperature rises to approximately 140°C due to excessive power dissipation in an over-current or short-circuit condition the internal thermal sense circuitry turns the power switch off, thus preventing the power switch from damage. Hysteresis is built into the thermal sense circuit allowing the device to cool down approximately 25° ...

... Due to the controlled rise times and fall times of the AP2166/AP2176, 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 AP2166/AP2176 also ensures that the switch is off after the card has been removed, and that the switch is off during the next insertion. ...
