The NX5P3363UK from NXP Semiconductors is a Current Limit Power Switch that has been designed for USB PD applications. It requires an input voltage of 4 - 5.5 V. This power switch has a built-in RCP recovery circuit for reverse current protection and reduces the voltage drop in a power source swap application. It has a programmable over-current limit threshold from 400 mA to 3.3 A, effectively clamping the output current to a safer threshold using an external resistor. This power switch has an on resistance of 35 milli-ohms with a high voltage tolerance on the VBUS pin to support USB PD applications. It is available in wafer-level package that measures 2.2 x 2.2 mm and is ideal for notebooks, ultrabooks, desktops, USB PD and type C port/hubs, tablets, and smartphone applications.
