ah175 hall effect latch for high temperature ah175 document number: ds31043 rev. 10 - 2 1 of 9 www.diodes.com july 2010 ? diodes incorporated description ah175 is a single-digital-output hall-effect latch sensor for high temperature operation. t he device includes an on-chip hall voltage generator for magnet ic sensing, an amplifier to amplify hall voltage, and a com parator to provide switching hysteresis for noise rejection, an open-collector output pre- driver. an internal band-gap regulator provides a temperature compensated supply voltage for internal circuits and allows a wide operating supply range. when the magnetic flux density ( b ) is larger than operate point ( bop ), output is switched on (out pin is pulled low). the output state is held on unt il a magnetic flux density reversal falls below brp. when b is less than brp, the output is switched off. the ah175 is available in sip-3l and sc59 packages. features ? bipolar hall-effect latch sensor ? 3.5v to 20v dc operating voltage ? open collector pre-driver ? 25ma output sink current ? built-in power reverse protection ? operating temperat ure: -40oc~+150oc ? sip-3l and sc59 packages (sc59 is commonly known as sot23 in asia) ? green molding compound (no br, sb) (note 1) pin assignments (top view) 1. vcc 2. gnd 3. out sip-3l 1. vcc gnd 2. 3. out (top view) sc59 applications ? rotor position sensing ? current switch ? encoder ? rpm detection notes: 1. eu directive 2002/95/ec (rohs). all applicabl e rohs exemptions applied. please visit our website at http://www.diodes.com/products/lead_free.html . typical application circuit m driver & control logic i a i b i c i a i c i b h b h a h c m: three phase hall motor digital hall effect sensor hall motor driver rpm sensing 3 phase hall motor
