product brief high sensitivity cmos hall-effe ct latch ah920 mar. 2010 bcd semiconductor manufacturing limited 1 description the ah920 is a hall-effect latch designed in mixed signal cmos technology. it is quite suitable for use in automotive, industrial and consumer applications. superior high-temperature performance is made possible through dynamic offset cancellation, which reduces the residual offset voltage normally caused by device over-molding, temperature dependencies, and thermal stress. the device integrates a voltage regulator, hall-voltage generator, small-signal amplifier, chopper stabilization, schmitt trigger, and open-drain output. an on-board regulator permits operation with supply voltage from 3.5v to 20v. the ah920 is available in to-92s-3 and sot-23-3 packages, which are optimized for most applications. features ? wide operating voltage range from 3.5 to ? 20v ? symmetrical switch points ? chopper-stabilized amplifier stage ? superior temperature stability ? open-drain output ? compact size ? esd rating: 6000v (human body model) applications ? brushless dc motor commutation ? brushless dc fan ? solid-state switch ? revolution counting ? speed detection ? high sensitivity and unconnected switch parametric table output saturation voltage (v cc =12v, i out =20ma) (mv) 185 supply current (average) (ma) 3 operating point (gauss) 22 releasing point (gauss) -22 hysteresis (gauss) 45 benefits ? high sensitivity for switching symmetry ? excellent temperature performance ? wide operation temperature range ? high esd ? cost-effective total solution if bundling ? with bcd?s fmd ics additional available materials ? samples ? preliminary data sheet ? reliability report ? esd report
