AH1807 MEDIUM SENSITIVITY MICROPOWER OMNIPLOAR HALL-EFFECT SWITCH Description Pin Assignments The AH1807 is a medium sensitivity micropower Omnipolar Hall Effect switch IC. It is designed for battery powered consumer products, home appliances, and industrial equipment such as smart meter magnetic tamper detect. Based on two Hall Effect plates and a chopper stabilized architecture, the AH1807 provides a reliable solution over the whole operating range. To support battery and low power applications, the design has been optimized to operate over the supply range of 2.5V to 5.5V and consumes only 24µW with a supply of 3V.

OUTPUT SC59 The single open drain output can be switched on with either a North or South pole of sufficient strength. When the magnetic flux density (B) perpendicular to the package is larger than operate point (Bop), the output is switched on (pulled low). The output is turned off when B becomes lower than the release point (Brp). The output will remain off when there is no magnetic field. 3 3. OUTPUT 2. GND 1.
