AH1913 ULTRA HIGH SENSITIVITY DIGITAL OMNIPOLAR HALL-EFFECT SWITCH Description Pin Assignments The AH1913 is an ultra-high sensitivity, digital-omnipolar, Hall effect SC59 switch IC from Diodes broad Hall effect switches family. Thanks to the hibernating clocking system, the average supply current is only 12A at 1.8V, which makes the AH1913 a perfect fit for battery-powered 2 OUTPUT consumer products, smart phones, E-meters, smoke detectors, and GND 3 IoT devices. AH1913 can operate wider range of supply voltage (1.6V 1 V DD to 5.5V) and supports low-voltage system microcontrollers, which provides great flexibility for system design. The advanced chopper- (Top View) stabilized design provides superior stability on switch-operating point over temperature and supply voltage range. The high ESD level of up (Top View) to 6KV helps improve the system robustness. V 1 4 OUTPUT DD 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 (B ), the OP output turns on (pulled low) and held until B is lower than release 2 3 NC GND point (B ).

Green Device (Note 3) Notes: 1. No purposely added lead. Fully EU Directive 2002/95/EC (RoHS), 2011/65/EU (RoHS 2) & 2015/863/EU (RoHS 3) compliant. 2. See Offset Cancellation AH1913 Typical Applications Circuit 1.6V to 5.5V V DD OUTPUT AH1913 C IN GND Note: 4. C is for power stabilization and to strengthen the noise immunity the recommended capacitance is 100nF typical and should be placed as close to IN the supply pin as possible.
