NX5P3290 - Power Switch

General Description

The NX5P3290 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.

Key Features

  • VIN supply voltage range from 4.0 V to 5.5 V.
  • All time reverse current protection with ultra fast RCP recovery.
  • Adjustable current limit from 400 mA to 3.3 A.
  • Clamped current output in overcurrent condition.
  • 29 V high voltage tolerance on VBUS pin.
  • Low ON resistance of the power FETs: 35 mī— (typical) in total.
  • Over temperature protection.
  • Safety approvals.
  • UL 62368-1, 2nd edition, file no. 20161017-E470128.
  • IEC 62368-1, 2nd edition, file no. DK-.

NX5P3290 USB PD and Type-C current-limited power switch Rev. 1.2 — 7 June 2019 Product data sheet 1. General description The NX5P3290 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 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 mA to 3.3 A, using an external resistor between the ILIM pin and GND pin.
