Load switches

Load switch power management to protect your electronic Systems

Load switches play a critical role in electronic systems. Load switch ICs are non-discrete electronic switches used for power management to control the power supply, by turning on and turning off a power rail to a load. It can reduce power consumption by turning off unused loads, providing power sequencing, providing inrush current control, over current limitation, short circuit protection, over temperature protection and active reverse current blocking. Nexperia load switches are suitable for a large range of industrial, consumer, computing and automotive applications.

Key features and benefits

  • Wide Input voltage: 2.5 V to 5.5 V
  • 110 mA to 2.5 A adjustable current limit to meet multiple applications
  • Fixed current limit version to simplify circuit design
  • Quick output discharge to prevent output from being floating
  • ILIM pin can be shorted to GND or floating to make system robust
  • 6% current limit accuracy at 1.2 A
  • Active reverse current blocking to prevent previous system from damage
  • 15 kV ESD Protection per IEC 61000-4-2
  • Constant-on or latch-off after over current

Applications

  • Laptops, notebooks and PCs
  • USB ports/hubs, docking station and desktops
  • Set top box
  • HDTV
  • VoIP phones
  • Printers
  • Optical socket protection
  • Current limiting circuits
