Diodes Incorporated’s Hall Switches Optimize Sensitivity

Diodes Incorporated (Nasdaq: DIOD), a leading global manufacturer and supplier of high-quality application specific standard products within the broad discrete, logic and analog semiconductor markets, today announced four 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 24µW with a 3V 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 ±30G and ±40G, the switches enable users to closely control the detection point. To suit 2.8V and 3.3V power rails, the switches’ supply range is specified at 2.5V to 3.6V. AH1806 and AH1808 are initially being provided in the SOT553 package, with SC59(SOT23) versions following in Q1’2013.

The medium sensitivity AH1807 and low sensitivity AH1809 Hall effect switches provide typical operating points of ±80G and ±130G respectively and are used in applications featuring much stronger field strengths, including smart meters, home appliances and security equipment. For added flexibility, the switches’ supply range is 2.5V to 5.5V and operating temperature range is extended, from -40ºC to +125ºC. There are two package options to choose from, SOT553 and the leaded SIP-3L, with SC59(SOT23) again following in Q1’2013.

Based on innovative chopper stabilized architecture, the switches assure high reliability over their full operating range and are characterized by superior temperature stability, minimal switch point drift and enhanced immunity to stress.
