NX5P2190 - Logic controlled high-side power switch

General Description

The NX5P2190 is an advanced power switch with adjustable current limit.

It includes under-voltage and over-voltage lockout, over-current, over-temperature, reverse bias and in-rush current protection circuits.

Key Features

  • Wide supply voltage range from 3 V to 5.5 V.
  • 30 V tolerant on VBUS.
  • ISW maximum 2 A continuous current.
  • Very low ON resistance: 100 m (maximum) at a supply voltage of 4.0 V.
  • Low-power mode (ground current 20 A typical).
  • 1.8 V control logic.
  • Soft start turn-on slew rate.
  • Protection circuitry.
  • Over-temperature protection.
  • Over-current protection with low current output mode.

NX5P2190 Logic controlled high-side power switch Rev. 1.1 — 15 January 2015 Product data sheet 1. General description The NX5P2190 is an advanced power switch with adjustable current limit. It includes under-voltage and over-voltage lockout, over-current, over-temperature, reverse bias and in-rush current protection circuits. These circuits are designed to isolate a voltage source from a VBUS interface pin automatically when a fault occurs. The device features two power switch terminals, one input (VINT) and one output (VBUS). A current limit input (ILIM) defines the over-current and in-rush current limit, and a voltage detect output (VDET) monitors the voltage level on VBUS. An open-drain fault output (FAULT) indicates when a fault condition occurs.
