... 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 AP2161/AP2171 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 AP2161/AP2171 implements a thermal sensing to monitor the operating junction temperature of the power distribution switch. Once the die temperature rises to approximately 145°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 AP2161/AP2171, 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 AP2161/AP2171 also ensures that the switch is off after the card has been removed, and that the switch is off during the next insertion. ...
