NPS4069 - 5.5V load switch

Description

The NPS4069 is a 5.5 V, 55 mΩ load switch suitable for applications up to 1.5 A.

The NPS4069 switch limits the output current to a constant current by using a constant-current mode when the output load exceeds the current limit threshold or shorted.

Features

  • Input operating voltage range (VIN): 2.5 V to 5.5 V.
  • Rated current (IMAX): 1.5 A.
  • ON resistance (RDS(on)):.
  • VIN = 5.5 V: 55 mΩ (typical).
  • VIN = 3.6 V: 65 mΩ (typical).
  • VIN = 2.5 V: 80 mΩ (typical).
  • Constant current during current limit.
  • No body diode when disabled (no current path from pin OUT to pin IN).
  • Active reverse voltage protection.
  • Built in soft start.
  • UL 62368 recognition.
  • SOT753.

NPS4069 5.5 V, 55 mΩ load switch with current limitation Rev. 2 — 11 March 2025 Product data sheet 1. General description The NPS4069 is a 5.5 V, 55 mΩ load switch suitable for applications up to 1.5 A. The NPS4069 switch limits the output current to a constant current by using a constant-current mode when the output load exceeds the current limit threshold or shorted. An internal voltage comparator disables the load switch when the output voltage is higher than the input to protect devices on the input side of the switch. The FLG pin is an active low output to indicate overcurrent, over temperature and reverse voltage conditions. 2. Features and benefits • Input operating voltage range (VIN): 2.5 V to 5.5 V • Rated current (IMAX): 1.5 A • ON resistance (RDS(on)): • VIN = 5.
