AH1912

NEW PRODUCT AH1912 ULTRA-LOW POWER DIGITAL OMNIPLOAR HALL-EFFECT SWITCH Description The AH1912 is an ultra-low power digital Omni-polar Hall Effect switch IC from Diodes broad Hall Effect switches family. Thanks to the hibernating clocking system, the average supply current is only 1.6μA at 3V, which makes the AH1912 perfectly fit battery-powered consumer products, Gas or water meter, smoke detectors and IoT devices. The wider range of supply voltage (1.6V to 5.5V) extends battery operating time and supports low voltage system microcontrollers, which provides great flexibility for system design. The advanced chopper stabilized design provides superior stability on switch operating point over temperature and supply voltage. The high ESD level up to 6kV helps to improve the system robustness. Pin Assignments (Top View) GND 3 2 OUTPUT 1 VDD SC59 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 operate point (BOP), the output will be turned on (pulled low) and held until B is lower than release point (BRP). The AH1912 comes with industry standard SC59 and X1-DFN1216-4 packages.
