Hall Switch IC

The AH1389 Hall-effect switch IC introduced by Diodes Incorporated offers a small, simple and versatile contactless switch solution and is specifically designed for battery-powered consumer equipment such as cellular phones, tablets, digital still and video cameras, while also embracing home appliances and industrial systems.

Applications and features

Applications include open/close detection for smart cover switches for cell phones and tablets, in addition to holster and dock detection for phones. It also features 360° rotation detection for display screens, video camera screen position detection, as well as position detection for doors, trays, selector switches and electronic locks in home appliances.

Dual outputs

The AH1389 is a unipolar Hall switch that offers high sensitivity with a tightly defined magnetic operating window across its full operating voltage and temperature range. It provides dual outputs for detecting north or south poles independently. Output 1 will switch on in the presence of a north pole with a magnetic flux strength that is below -25G and release when the flux exceeds -20G. Similarly, output 2 will switch in the presence of a south pole with a magnetic flux magnitude greater than +25G and release when the flux magnitude falls below +20G.

Temperature range

Optimized for portable and battery-powered applications, the micropower AH1389 operates from a 1.6V to 3.6V supply while consuming an average current of only 4μA. The device is specified for operation over a -40°C to +85°C temperature range and provides a high ESD rating of 8kV for improved reliability and ease of handling during end-equipment manufacture.
