OCH1661 Micro Power Omnipolar Hall-effect Sensor Switch  General Description  Features The OCH1661 Omnipolar Hall effect sensor IC is  1.9uA Micro power design fabricated from mixed signal CMOS technology. It is  Operation with North or South pole(omnipolar) comprised of two Hall plates and a CMOS output driver,  CMOS Output mainly designed for battery-operation. The total power  1.65V to 5.5V battery operation consumption in normal operation is typically 3.6μW with  High sensitivity and high stability of the magnetic a 1.8V power source. either north or south poles of switching points sufficient strength will turn the output on. The output will  High resistance to mechanical stress be turned off under no magnetic field. While the  Digital output signal magnetic flux density (B) is larger than operating point  Good RF noise immunity (BOP), the output will be turned on (low), the output is  -40 ℃to 85℃operating temperature held until B is lower than release point (BRP), and then  SOT23-3L/SIP-3L(TO92S) package turned off.  Applications The OCH1661 is available in many flexible packaging  Smart meter options, such as SOT23-3L/SIP-3L. Operating  toys temperature range of the OCH1661 is from -40°C to  Cover switch in Notebook PC/PDA 85°C.  Contact-less switch in consumer products  Solid State Switch
