NEW PRODUCT AH1903 HIGH SENSITIVITY MICROPOWER UNIPOLAR/OMNIPOLAR SELECTABLE HALL-EFFECT SWITCH Description The AH1903 is a high sensitivity micropower Omnipolar or Unipolar selectable Hall effect switch IC with internal pull up and pull down capability. Designed for battery powered consumer equipment such as cellular phones and portable PCs to office equipment, home appliances and industrial applications, the average supply current is only 4.3µA at 1.8V. To support portable equipment the AH1903 can operate over the supply range of 1.6V to 3.6V and uses a hibernating clocking system to minimize the power consumption. To minimize PCB space the AH1903 is available in a small low profile X1-DFN1216-4 package.
