NX5P3090
USB PD and type C current-limited power switch
Rev. 1 — 1 August 2016
Product data sheet
1. General description
The NX5P3090 is a precision adjustable current-limited power switch for USB PD
application. The device includes under voltage lockout, over-temperature 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 over-current limit threshold;
an open-drain fault output (FAULT) indicates when a fault condition has occurred.
The over-current limit threshold can be programmed from 400 mA to 3.3 A, using an
external resistor between the ILIM pin and GND pin. In the over current condition, the
device will clamp the output current to the value set by ILIM and keep the switch on while
assert the FAULT flag. To minimize current surges during turn on, the device has built in
soft start which controls the power switch rise time.
Surge protection has been integrated in the device to enhance system robustness. The
enable input includes integrated logic level translation making the device compatible with
lower voltage processors and controllers.
NX5P3090 is offered in a 12 bump 1.35 x 1.65 mm, 0.4 mm pitch WLCSP package.
