Diodes Incorporated – AH1389: Miniature Micropower, Dual-Output, Unipolar Hall Switch


The AH1389 is a miniature micropower magnetic Unipolar Hall effect switch IC with dual outputs specifically designed for portable and battery-powered consumer equipment to home appliances and industrial applications. To support battery-powered equipment and low voltage microcontrollers, the AH1389 can operate over the supply range of 1.6V to 3.6V and uses a sleep function to give an average supply current of only 4μA at 1.85V. The AH1389 has an 8kV ESD rating on the supply and output pins. The small low profile X2-DFN1410-4 package minimizes PCB space.
