ah1809 document number: ds35523 rev. 3 - 2 1 of 13 www.diodes.com february 2014 ? diodes incorporated a h1809 low sensitivity micropower omniploar hall-effect switch description the ah1809 is a low sensitivity mi cro power omnipolar hall effect switch ic designed for battery powered consumer to home appliance and industrial equipment such smart e-meters. based on two hall effect plates and a chopper stabilized architecture the ah1809 provides a reliable solution over the whole operating range. to support battery and low power app lications the design has been optimized to operate over the supply range of 2.5v to 5.5v and consumes only 24w with a supply of 3v. the single open drain output can be switched on with either a north or south pole of sufficient strengt h. when the magnetic flux density perpendicular to the package (b) is larger than operate point (bop) the output is switched on (pulled low). the output is turned off when b becomes lower than the release point (brp). the output will remain off when there is no magnetic field. the ah1809 is available in sc59, sot553 and sip-3l. features ? omnipolar (north or south pole) operation ? low sensitivity ? single open drain output ? micropower operation ? 2.5v to 5.5v operating range ? chopper stabilized design provides ? superior temperature stability ? minimal switch point drift ? enhanced immunity to stress ? good rf noise immunity ? -40c to +125c operating temperature ? high esd ? small low profile sot553 and industry standard sc59 and sip-3l packages ? totally lead-free & fully rohs compliant (notes 1 & 2) ? halogen and antimony free. ?green? device (note 3) pin assignments top view) sc59 (top view) sot553 (top view) 1. v dd 2. gnd 3. output sip-3l applications ? smart e-meters ? tamper protection switch ? door, lids and tray position switch ? proximity and position switches ? level detects ? on/off switch digital contact-less switch in industrial and consumer products notes: 1. no purposely added lead. fully eu directiv e 2002/95/ec (rohs) & 2011/6 5/eu (rohs 2) compliant. 2. see http://www.diodes.com/quality/lead_free.html for more in formation about diodes incorporated?s definitions of halogen- a nd 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.
