Bipolar, Latching, and Unipolar Hall-effect Digital Position Sensor ICs: SS400 Series, SS500 Series 32320997 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 -40°C to 150°C [-40°F to 302°F] • 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 The SS400 Series and SS500 Series are small and versatile digital Hall-effect devices that are operated by the magnetic field from a permanent magnet or an electromagnet, and are designed to respond to alternating North and South poles, or to a South pole only. They are available in bipolar, latching or unipolar magnetics. On-board regulation provides stable operation over a 3.8 Vdc to 30 Vdc supply voltage range. These sensors are capable of continuous 20 mA sinking output and may be cycled as high as 50 mA max. The 3.8 V capability allows for use in many potential low voltage applications. The digital, open collector sinking-type output is easily interfaced with a wide variety of electronic circuits. To provide reliable products and consistent quality, the SS400 Series products are tested at both 25°C [75°F] and 125°C [257°F]. All catalog listings are qualified for operation up to 150°C [302°F].
