Diodes Incorporated Announces New Omnipolar Hall Switches That Reduce Power Consumption and Simplify Production

Feb 6, 2009
DALLAS, Feb 06, 2009 (BUSINESS WIRE) -- Diodes Incorporated (NASDAQ:DIOD), a leading global manufacturer and supplier of application specific standard products within the broad discrete and analog semiconductor markets, today introduced two low voltage Omnipolar parts that substantially reduce power consumption in battery-powered, hand-held devices and dramatically simplify production processes, adding to its extensive range of cost effective Hall effect sensor switches. End-market uses include contact-less lid or display orientation and position detection tasks in notebooks, mobile phones, digital still cameras and camcorders.

Operating over a wide supply voltage range, the micro-power AH1802 and AH1888 Hall effect sensor switches support a broad range of battery cell configurations, from single cell Lithium Ion to dual cell alkaline/zinc. As an illustration of its low power operation, the AH1888 consumes just 15 micro-watts for a supply voltage of 1.8 volts.

The AH1802 and AH1888 detect the magnetic field generated by both North and South poles, thereby removing the requirement for production processes to manage magnet orientation. In the presence of a local magnetic field, the sensor produces a low level 'on' output signal.

The AH1802 with an open drain, single output offers very high sensitivity that makes it ideal for sensing vertically oriented or smaller sized magnets. Packaged in an ultra thin 0.4mm height DFN2015, the compact AH1802 fits slider style mobile phones where height is critical. Offered in the low profile SOT-553 package, the AH1888's dual complementary push-pull outputs enable the device to be directly connected to a system processor without the use of pull up resistors. Outputs adjust to polarity changes, allowing the device to support key wheel type magnets, which are used to detect position and orientation for displays or keyboards that pivot or rotate.

The sensors' chopper stabilization circuitry delivers superior temperature stability, making them less sensitive to physical stress and guards against switch-point drift. Both devices support an operating temperature range from -40C to 85C.

The AH1802 is priced at $0.30USD in 1K quantities and the AH1888 at $0.35USD in 1K quantities.
