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

SC59 The single push-pull for AH1911 or open drain for AH1921 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 AH1911/AH1921 comes with industry standard SC59 package. Features Applications 
