AH1902 HIGH SENSITIVITY MICROPOWER OMNIPLOAR HALL-EFFECT SWITCH NEW PRODUCT Description Pin Assignments The AH1902 is a high-sensitivity micropower Omnipolar Hall effect switch IC with internal pull up and pull down capability. Designed for portable and battery powered consumer equipment such as cellular phones and portable PCs to office equipment, home appliances and industrial applications, the average supply current is only 4.3μA at 1.8V. To support potable equipment the AH1902 can operate over the supply range of 1.6V to 3.6V and uses a hibernating clocking system to minimize the power consumption. To minimize PCB space, the AH1902 is available in small low profile X1-DFN1216-4, X2-DFN2015-6 and SOT553 packages.

EU Directive 2002/95/EC (RoHS) & 2011/65/EU (RoHS 2) compliant. All applicable RoHS exemptions applied. 2. See http://www.diodes.com/quality/lead_free.html for more information about Diodes Incorporated’s definitions of Halogen- and Antimony-free, "Green" and Lead-free. 3. Halogen- and Antimony-free "Green” products are defined as those which contain <900ppm bromine, <900ppm chlorine (<1500ppm total Br + Cl) and <1000ppm antimony compounds. Typical Applications Circuit 1.6V to 3.6V VDD CIN AH1902 OUTPUT GND Note: 4. CIN is for power stabilization and to strengthen the noise immunity, the recommended capacitance is 100nF typical and should be placed as close to the supply pin as possible.
