The SS441A is a temperature compensated digital hall effect sensor IC in 3 pin TO-92 package. This small, versatile digital hall effect device is operated by magnetic field from permanent magnet or an electromagnet. It is designed to respond to alternating north and south poles or to south pole only. Band gap regulation provides stable operation over 3.8VDC to 30VDC supply voltage range. The SS441A 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 wide variety of electronic circuits.
