Diodes Incorporated AH1889
AH1889 is a high sensitivity dual output Unipolar Hall effect IC which can detect either a North or South pole independently and switch one of its two outputs with internal pull up and pull down capability. The AH1889 is mainly designed for low voltage applications which require a quick response time and can operate over the supply voltage of 1.65V to 3.6V.| Part No. | AH1889 |

DESCRIPTION
To minimize PCB space AH1889 outputs have internal pull up and pull down capability and is packaged in a small low profile SOT553 package. A South pole of sufficient strength will turn OUTPUT1 on and a North Pin Assignments (Top View) NEW PRODUCT pole of sufficient strength with turn on OUTPUT2. While the magnetic flux density (B) perpendicular to the package is larger than operate point Bops or Bopn, the appropriate output will be turned on (pulled low), the output is held until B is lower than release point Brps or Brps, then turned off (high). The outputs will be turned off and will remain off when there is no magnetic field. SOT553FEATURES
