Diodes AH3360-Z-7 is a high sensitivity micropower Unipolar Hall effect switch IC with internal pull up and pull down capability. Designed for battery powered consumer such as cellular phones and portable PCs to home appliance and industrial equipment, the average supply current is only 4.3uA at 1.85V. To support portable equipment the AH3360-Z-7 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 AH3360-Z-7 is available in small low profile SOT553, X1-DFN1216-4 and X2-DFN2015-6 and packages. The output is activated with a south pole of sufficient magnetic field strength. When the magnetic flux density (B) perpendicular to the package is larger than operate point (Bop), the output will be turned on (pulled low) and held until B is lower than release point (Brp). The output will remain off when there is no magnetic field.
