SS449A

SS449A is a SS400 series, unipolar, temperature compensated digital hall effect sensor IC. It is 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. Band gap regulation provides stable operation over 3.8Vdc to 30Vdc supply voltage range. This sensor is capable of continuous 20mA sinking output and may be cycled as high as 50mA max. 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. It is used in applications such as transportation, industrial, medical.
