NX5P2553 - Precision adjustable current-limited power switch

Datasheet Summary

Description

The NX5P2553 is a precision adjustable current-limited power switch.

The device includes undervoltage lockout, overtemperature, and reverse bias protection circuits designed to isolate the switch terminals when a fault condition occurs.

Features

  • Wide supply voltage range from 2.5 V to 5.5 V.
  • ISW maximum 1.5 A continuous current.
  • 6 % current-limit accuracy at 1.8 A (typical).
  • Meets USB current-limiting requirements.
  • Adjustable current limit from 85 mA to 1800 mA (typical).
  • Constant current mode in overcurrent situation.
  • Overtemperature protection.
  • Very low ON resistance: 95 m (typical) for TSOP6 package.
  • Fast short-circuit switch-off response (2.0 s typical).
  • ILIM short detection.

NX5P2553 Precision adjustable current-limited power switch Rev. 1 — 6 July 2015 Product data sheet 1. General description The NX5P2553 is a precision adjustable current-limited power switch. The device includes undervoltage lockout, overtemperature, and reverse bias protection circuits designed to isolate the switch terminals when a fault condition occurs. It also has an overcurrent protection circuit to limit the output current. The device features two power switch terminals, one input (VIN), and one output (VOUT). It also consists of a current limit input (ILIM) for defining the overcurrent limit, an open-drain fault output (FAULT) to indicate when a fault condition has occurred, and an enable input (EN) to control the state of the switch.
