ah175 hall effect latch for high temperature ah175 rev. 3 1 of 8 december 2006 www.diodes.com ? diodes incorporated lead-free lead-free ? bipolar hall effect latch sensor ? 3.5v to 20v dc operation voltage ? open collector pre-driver ? 25ma output sink current ? chip power reverse-connection protection ? operating temperature: -40 o c~150 o c ? lead free finish/rohs compliant for lead free products (note 1) ? package: sip-3l, sc59-3l ah175 is a single-digital-output hall-effect sensor for high temperature operation. the device includes an on-chip hall voltage generator for magnetic sensing, an amplifier to amplify hall voltage, and a comparator to provide switching hysteresis for noise rejection, and an open-collector output pre-driver. an internal band-gap regulator is used to provide temperature compensated supply voltage for internal circuits and allows a wide operating supply range. while the magnetic flux density (b) is larger than threshold bop, the out pin turns on (low). if b removed toward brp, the out pin is latched ?on? state prior to b < brp. when b < brp, the out pin go into ? off ? state. ? rotor position sensing ? current switch ? encoder ? rpm detection ordering information ah 175 x x x -x packing -7 : -b : -a : taping bulk (note 3) ammo box (note 4) p: sip-3l w: sc59-3l package lead-free l : lead free magnetic characteristics a or b - note: 1. rohs revision 13.2.2003. glass and hi gh temperature solder exemptions applied, see eu directive annex notes 5 and 7 . note: 2. pad layout as shown on diodes inc. suggested pad layout document ap02001, which ca n be found on our website at http://www .diodes.com/datasheets/ap02001.pdf. 3. bulk is for sip-3 straight lead. 4. ammo box is for sip-3 spread lead. features general description applications tube/bulk 7? tape and reel ammo box device package code packaging (note 2) quantity part number suffix quantity part number suffix quantity part number suffix ah175-p p sip-3l 1000 -b na na 4000/box -a ah175-w w sc59-3l na na 3000/tape & reel -7 na na
