    AH1911/AH1921
    ULTRA-LOW POWER DIGITAL OMNIPLOAR
    HALL-EFFECT SWITCH NEW PRODUCT Description Pin Assignments The AH1911/AH1921 is an ultra-low power digital Omnipolar 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 AH1911/AH1921
    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. (Top View) 2 OUTPUT

Подробное описание

The AH1921 is an ultra-low power digital Omnipolar Hall Effect switch IC from Diodes broad Hall Effect switches family. Thanks to the hibernating clocking system, the average supply current is only 1.6?A at 3V, which makes the AH1921 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.

The open drain output can be switched on with either South or North pole of sufficient 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 AH1921 comes with industry standard SC59 package.
