ah180n document number: ds32174 rev. 4 - 2 1 of 8 www.diodes.com august 2012 ? diodes incorporated a h180n micropower omnipolar hall-effect switch description the ah180n is a high sensitivity, micro power omnipolar hall effect switch ic designed for portable and battery powered equipment such as cellular phones, pda? s and portabl e pc? s. based on two sensitive hall effect plates and a chopper stabilized architecture the ah180n provides a reliable solution over the whole operating range. to support portable and battery powered equipment the design has been optimized to operate over the supply range of 2.5v to 5.5v and consumes only 24a with a supply of 3v. the single open drain output can switched on with either a north or south pole of sufficient strength. when the magnetic flux density (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. features ? omnipolar (north or south pole) operation ? high 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 +85c operating temperature ? esd (hbm) > 6kv ? sc59 (sot23), tsot23, and sot553 low profile packages ? totally lead-free & fully rohs compliant (notes 1 & 2) ? halogen and antimony free. ?green? device (note 3) pin assignments applications ? cover switch in clam-shell or slide type cellular phones ? display switch for portable pcs ? on/off switch for pdas and digital cameras ? contact-less switch in 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 for more in formation about diodes incorpor ated?s definitions of halogen- and antimony-free, "gree n" and lead-free. 3. halogen- and antimony-free "green? products are defined as those which contain <900ppm br omine, <900ppm chlorine (<1500ppm t otal br + cl) and <1000ppm antimony compounds.
