AH1913
ULTRA HIGH SENSITIVITY
DIGITAL OMNIPOLAR HALL-EFFECT SWITCH
Description
The AH1913 is an ultra-high sensitivity, 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 12μA
at 1.8V, which makes the AH1913 a perfect fit for battery-powered
consumer products, smart phones, E-meters, smoke detectors, and
IoT devices. AH1913 can operate wider range of supply voltage (1.6V
to 5.5V) 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 range. The high ESD level of up
to 6KV helps improve the system robustness.
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 turns on (pulled low) and held until B is lower than release
point (BRP).
The AH1913 comes with industry standard SC59 and X1-DFN1216-4
