AH182/ah183 low power hall effect switch AH182/ah183 rev. 2 1 of 9 march 2007 www.diodes.com ? diodes incorporated ? micropower operation ? 2.5v to 5.5v battery operation ? offset canceling technology ? superior temperature stability ? extremely low switch-point drift ? insensitive to physical stress ? -40 c to 85 c operating temperature ? sip-3l/sc59 package ? lead free finish/rohs compliant for lead free products (note 1) AH182/ah183 is a three-terminal ha ll effect sensor device with an output driver, mainly des igned for battery?operation, hand-held equipment (such as cellular and cordless phones, and pda?s) the total operation power is down to 15uw in the 2.75v supply. the south pole of sufficient streng th will turn the output on in sip-3l but the north pole of sufficient strength will turn the output on in sc59 package. the output will be turned off under no magnetic field. while the magnetic flux density (b) is larger than operation point (bop) , the output will be turned on (low), the output is held until b is lower than the release point (brp), then turned off. the difference between AH182 and ah183 is that the former consumes less power than that of the latter in the hall sensor operation. ? cover detector ? speed measurement ? home safety AH182/ah183 x - x x x packing p: sip-3l w: sc59 package lead l : lead free wafer body blank or a~z : if necessary to specify cmos hall- effect switch spread-leg ammo pack for sip-3l; blank : bulk a : tape & reel for sot23-3l (note 2) note: 1. rohs revision 13.2.2003. glass and high temperature solder exemptions applied, see eu directive annex notes 5 and 7 . 2. pad layout as shown on diodes inc. suggested pad layout document ap02001, which can be found on our website at http://www.diodes.com/d atasheets/ap02001.pdf . features general description pin descriptions applications name p/i/o pin # description vdd p/i 1 power supply input gnd p 2 ground output o 3 output pin ordering information
