 Diodes Inc., a leading global manufacturer and supplier of high-quality application specific standard products within the broad discrete, logic, and analog semiconductor markets, has announced omnipolar Hall Effect switches offering sensitivities to closely match the magnetic field strengths, used in proximity and position detection duties in a variety of different product designs. These micropower devices have also been optimized for battery and low power operation, typically consuming just 24 μW with a 3 V supply.
Suitable for portable consumer devices including cell phones, PDAs and laptops, as well as industrial products, the high sensitivity AH1806 and AH1808 are each designed using two Hall Effect plates. With operating thresholds set at ±30 G and ±40 G, the switches enable users to closely control the detection point. To suit 2.8 V and 3.3 V power rails, the switches’ supply range is specified at 2.5 V to 3.6 V. |
