NX5P3363-Q100
description
The NX5P3363/Q100 is a precision adjustable current-limited power switch for USB PD application. The device includes undervoltage lockout, overtemperature protection, and reverse current protection circuits to automatically isolate the switch terminals when a fault condition occurs. The 29 V tolerance on VBUS pin ensures the device is able to work on a USB PD port; a current limit input (ILIM) pin defines the overcurrent limit threshold; an open-drain fault output (FLT) indicates when a fault condition has occurred.
The overcurrent limit threshold can be programmed from 400 m A to 3.3 A, using an external resistor between the ILIM pin and GND pin. In the overcurrent condition, the device clamps the output current to the value set by ILIM and keeps the switch on while asserting the FLT flag.
To minimize current surges during normal turn on, the device has built-in soft start by limiting the power switch turn on slew rate. However, user can disable the soft start and request...
