AH182/AH183 is a three-terminal Hall effect sensor device withan output driver, mainly designed for battery–operation,hand-held equipment (such as cellular and cordless phones, andPDA’s) The total operation power is down to 15uW in the 2.75Vsupply.The south pole of sufficient strength will turn the output on inSIP-3L but the north pole of sufficient strength will turn the outputon in SC59 package. The output will be turned off under nomagnetic field.While the magnetic flux density (B) is larger than operation point(Bop), the output will be turned on (low), the output is held untilB is lower than the release point (Brp), then turned off. Thedifference between AH182 and AH183 is that the formerconsumes less power than that of the latter in the Hall sensoroperation.
