10 pcs : AH1893-Z-7 - Board Mount Hall Effect/Magnetic Sensors Hall Effect Switch 1.6V to 3.6V 4.3uA

AH1893 Omnipolar Hall Effect Switch IC Diodes AH1893 is a high sensitivity micropower Omnipolar Hall Effect Switch IC with internal pull-up and pull-down capability. Designed for portable and battery-powered equipment such as cellular phones and portable PCs to home appliances and industrial applications, the average supply current is only 4.3µA at 1.85V. To support portable equipment the AH1893 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 AH1893 is available in small low profile X1-DFN1216-4 and SOT553 packages. The output is activated with either a north or south pole of sufficient magnetic field strength. When the magnetic flux density (B) perpendicular to the package is larger than the operate point (Bop), the output will be turned on (pulled low) and held until B is lower than the release point (Brp).
