Bipolar, Latching, and Unipolar Hall-effect Digital 32320997 Position Sensor ICs: SS400 Series, SS500 Series Issue B Datasheet FEATURES Quad Hall IC design minimizes mechanical stress effects Temperature-compensated magnetics help provide stable operation over a wide temperature range of -40C to 150C -40F to 302F Broad, inclusive supply voltage capability from 3.8 Vdc to 30 Vdc for application flexibility Digital, open collector sinking output for easy interfacing with a variety of common electronic circuits High sensitivity versions available for potential applications requiring high accuracy or wide gaps Bipolar, latching or unipolar magnetics DESCRIPTION POTENTIAL APPLICATIONS The SS400 Series and SS500 Series are small and versatile Industrial: Speed and RPM (revolutions per minute) sensing, digital Hall-effect devices that are operated by the magnetic tachometer, counter pickup, flow-rate sensing, brushless dc field from a permanent magnet or an electromagnet, and (direct current) motor commutation, motor and fan control, are designed to respond to alternating North and South robotics control poles, or to a South pole only. They are available in bipolar, Transportation: Speed and RPM (revolutions per minute) latching or unipolar magnetics. On-board regulation provides sensing, tachometer, counter pickup, motor and fan control, stable operation over a 3.8 Vdc to 30 Vdc supply voltage electric window lift, convertible roof position range. These sensors are capable of continuous 20 mA Medical: Motor assemblies, medication dispensing control sinking output and may be cycled as high as 50 mA max. The 3.8 V capability allows for use in many potential low PORTFOLIO voltage applications. The digital, open collector sinking-type Other bipolar, latching and unipolar Hall- output is easily interfaced with a wide variety of electronic effect digital sensor ICs include: circuits.
