AH1806/08 Omnipolar Hall Effect Switches Diodes Incorporated AH1806 / AH1808 High Sensitivity Micropower Omnipolar Hall Effect Switches provide a small and simple contactless switch solution for portable and battery powered applications. Based on two high sensitivity Hall Effect plates and chopper stabilized architecture, the AH1806 and AH1808 provide a reliable solution over the whole operating range. These high sensitivity Hall effect switches have been optimized to operate over the supply range of 2.5V to 3.6V and use a micropower sleep function to give an average supply current of only 8uA. AH1806 and AH1808 have open drain output for flexibility.
