... 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 AP2162/AP2172 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 ...

... Due to the controlled rise times and fall times of the AP2162/AP2172, 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 AP2162/AP2172 also ensures that the switch is off after the card has been removed, and that the switch is off during the next insertion. ...
