The unipolar switching characteristic makes these devices ideal for use with a simple bar or rod magnet. Thanks to its wide operating voltage range and extended choice of temperature range, it is quite suitable for use in automotive, industrial and consumer applications. The SS119 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 25 mA. With suitable output pull up, they can be used with bipolar or CMOS logic circuits. The device is delivered in a Small Outline Transistor (SOT) or in a Plastic Single In Line (SIP 3L flat). Both 3-lead packages are RoHS compliant. These Hall-effect switches are monolithic integrated circuits with tighter magnetic specifications, designed to operate continuously over extended tem 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 SS119 Unipolar Hall-Effect Digital Switch Pin Definitions and Descriptions SOT Pin № SIP Pin № Name Type 1 1 VDD Supply Supply Voltage pin 2 3 OUT Output Open Drain Output pin 3 2 GND Ground Ground pin Function Absolute Maximum Ratings Parameter Symbol Value Units Supply Voltage VDD 28 V Supply Current IDD 50 mA Output Voltage VOUT 28 V Output Current IOUT 50 mA Storage Temperature Range TS Operating Temperature Range Symbol Value Temperature Suffix “E” TA -40 to 85 °C Temperature Suffix “K” TA -40 to 125 °C Temperature Suffix “L” TA -40 to 150 °C -65 to 170 °C Units Exceeding the absolute maximum ratings may cause permanent damage.
