AH1809 LOW SENSITIVITY MICROPOWER OMNIPLOAR HALL-EFFECT SWITCH Description 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. The single open drain output can be switched on with either a North or South pole of sufficient strength.
