The SS461A is a temperature compensated Digital Hall-effect Sensor IC designed to respond to alternating North and South poles or to a South-pole only. This is a small, versatile, digital hall-effect device that is operated by the magnetic field from a permanent magnet or an electromagnet. Band gap regulation provides stable operation over 3.8 to 30VDC supply voltage range.
This sensor is capable of continuous 20mA sinking output and may be cycled as high as 50mA maximum. Its 3.8V 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.
