AH1889
HIGH SENSIVITY DUAL UNIPOLAR HALL-EFFECT SWITCH
Description
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. 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
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.

Notes:
1. No purposely added lead. Fully EU Directive 2002/95/EC (RoHS) & 2011/65/EU (RoHS 2) compliant.
2. See http://www.diodes.com/quality/lead_free.html for more information about Diodes Incorporated’s definitions of Halogen- and Antimony-free, "Green"
and Lead-free.
3. Halogen- and Antimony-free "Green” products are defined as those which contain <900ppm bromine, <900ppm chlorine (<1500ppm total Br + Cl) and
<1000ppm antimony compounds.
Typical Applications Circuit
Note:
4. CIN is for power stabilization and to strengthen the noise immunity, the recommended capacitance 100nF typical.

Notes:
6. Stresses greater than the 'Absolute Maximum Ratings' specified above may cause permanent damage to the device. These are stress ratings only;
functional operation of the device at these or any other conditions exceeding those indicated in this specification is not implied. Device reliability may be
affected by exposure to absolute maximum rating conditions for extended periods of time.
7. The absolute maximum VDD of 6V is a transient stress rating and is not meant as a functional operating condition. It is not recommended to operate the
device at the absolute maximum rated conditions for any period of time.
