SS133 Unipolar Hall-Effect Digital Switch General Description The SS133 is a unipolar Hall-effect sensor IC fabricated from bipolar technology. The device integrates a voltage regulator, reverse battery protection diode, Hall sensor with dynamic offset cancellation system, temperature pensation circuitry, small signal amplifier, Schmitt trigger and an open-collector output to sink up to 50 m A. With suitable output pull up, they can be used with bipolar or CMOS logic circuits. These Hall-effect switches are monolithic integrated circuits with tighter magnetic specifications, designed to operate continuously over extended temperatures to +150°C,and are more stable with both temperature and supply voltage changes. Internal pensation characteristic makes the sensitivity increase slightly with temperature increasing, so that this IC is Particularly suitable to be used with the monly low-cost magnets. If a magnetic flux density larger than threshold Bop, Output is turned on (low). When a magnetic flux density reversal falls below Brp, Output will be turned off (high). Thanks to its wide operating voltage range,extended choice of temperature range and high reliability, it is quite suitable for use in automotive, industrial and consumer applications.
