AH1809 LOW SENSITIVITY MICROPOWER OMNIPLOAR HALL-EFFECT SWITCH Description Pin Assignments The AH1809 is a low sensitivity micropower Omnipolar Hall Effect switch IC. It is designed for battery powered consumer products, home appliances, and industrial equipment such smart e-meters. Based on two Hall Effect plates and a chopper stabilized architecture the AH1809 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. TOP View) GND 3 OUTPUT 1 VDD 2 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 perpendicular to the package (B) 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. (TOP View) The AH1809 is available in SC59, SOT553 and SIP-3L.
