Internal compensation characteristic makes the sensitivity increase slightly with temperature increasing, so that this IC is Particularly suitable to be used with the commonly 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. 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 compensation circuitry, small signal amplifier, Schmitt trigger and an open-collector output to sink up to 50 mA. 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 Glossary of Terms MilliTesla (mT), Gauss Units of magnetic flux density: 1mT = 10 Gauss RoHS Restriction of Hazardous Substances Operating Point (BOP) Magnetic flux density applied on the branded side of the package which turns the output driver ON (VOUT = VDSon) Release Point (BRP) Magnetic flux density applied on the branded side of the package which turns the output driver OFF (VOUT = high) 2 V3.10 Nov 1, 2013 SS133 Unipolar Hall-Effect Digital Switch Pin Definitions and Descriptions SOT Pin № Name Type 1 VDD Supply Supply Voltage pin 2 GND Ground Ground pin 3 OUT Output Open Collector Output pin Function Absolute Maximum Ratings Symbol Parameter Value Units Supply Voltage VDD 60 V Reverse Voltage VDD -24 V Output Voltage VOUT 30 V Output Current IOUT 50 mA Magnetic Flux Density B No limit Operating Temperature Range TA -40 to +150 °C Storage Temperature Range TS -65 to 170 °C Maximum Junction Temperature TJ +150 °C Lead Temperature(Solding, TL +250 °C PD 450 mW Value Units 5 sec) Package Power Dissipation Operating Temperature Range Symbol Temperature Suffix “E” TA -40 to 85 °C Temperature Suffix “K” TA -40 to 125 °C Temperature Suffix “L” TA -40 to 150 °C Exceeding the absolute maximum ratings may cause permanent damage.
