Description
The AP2146 and AP2156 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.

... In the third condition, the load has been gradually increased beyond the recommended operating current. The current is permitted to rise until the current-limit threshold (I the device is exceeded. The AP2146/AP2156 is capable of delivering current up to the current-limit threshold without damaging the device. Once the threshold has been reached, the device switches into its current limiting mode and is set at I ...

... Thermal Protection Thermal protection prevents the IC from damage when heavy-overload or short-circuit faults are present for extended periods of time. The AP2146/AP2156 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 AP2146/AP2156, 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 AP2146/AP2156 also ensures that the switch is off after the card has been removed, and that the switch is off during the next insertion. ...
