The AH1902 is a high-sensitivity, micropower Omnipolar Hall effect switch IC designed for portable and battery-powered consumer and industrial applications. It features internal pull-up and pull-down capability, low average supply current (4.3A at 1.8V), and a wide operating supply range (1.6V to 3.6V). Its hibernating clocking system minimizes power consumption, and it is available in small, low-profile packages to save PCB space. The output is activated by either a north or south pole of sufficient magnetic field strength.
