AH1807/9 Hall Effect Switches


AH1807 medium sensitivity and AH1809 high sensitivity micropower, omnipolar Hall Effect switches from Diodes Inc.


Diodes' AH1807/9 Hall Effect SwitchesDiodes Inc., a leading global manufacturer and supplier of high-quality application specific standard products within the broad discrete, logic, and analog semiconductor markets, has announced omnipolar Hall Effect switches offering sensitivities to closely match the magnetic field strengths, used in proximity and position detection duties in a variety of different product designs. These micropower devices have also been optimized for battery and low power operation, typically consuming just 24 μW with a 3 V supply.

The medium sensitivity AH1807 and low sensitivity AH1809 Hall Effect switches provide typical operating points of ±80 G and ±130 G, respectively, and are used in applications featuring much stronger field strengths, including smart meters, home appliances, and security equipment. For added flexibility, the switches’ supply range is 2.5 V to 5.5 V and operating temperature range is extended from -40°C to +125°C.

Applications
  • Smart E-meters
  • Tamper protection switch
  • Doors, lids, and tray position detect switches
  • Consumer and industrial contactless switches
  • Level detect
