  Diodes Incorporated’s Hall Switches Optimize Sensitivity

Business Wire

PLANO, Texas -- November 27, 2012

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

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. For further information, visit the Company’s website at
