NX5P3290UKZ Product Details

The NX5P3290 is a precision adjustable current-limited power switch for USB PD application. Thedevice includes under voltage lockout, over-temperature protection, and reverse currentprotection circuits to automatically isolate the switch terminals when a fault conditionoccurs. The 29 V tolerance on VBUS pin ensures the device is able to work on a USB PDport; a current limit input (ILIM) pin defines the over-current limit threshold; anopen-drain fault output (FLT) indicates when a fault condition has occurred.

The over-current limit threshold can be programmed from 400 mA to 3.3 A, using anexternal resistor between the ILIM pin and GND pin. In the over current condition, thedevice will clamp the output current to the value set by ILIM and keep the switch onwhile asserting the FLT flag.

To minimize current surges during normal turn on, the device has built in soft start bylimiting the power switch turn on slew rate. However, user can disable the soft startand request a fast output by pulling FO pin HIGH.

A fast RCP recovery circuit has been added to the switch to prevent any reverse currentflowing back to power source at all times. When exiting from reverse current protectionstate, the power MOSFET will turn on within 50 us. The fast RCP recovery ensures thevoltage on VBUS doesn’t drop too much in a power source swap application.

NX5P3290 is offered in a 2.05 x 2.05 mm, 16 bump WLCSP package.
