The device 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.
The AH1389 is a unipolar Hall switch 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.
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. It is supplied in a small, low-profile X2-DFN1410-4 package.
