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 GND 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. 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 device is delivered in a Small Outline Transistor (SOT) and in a Plastic Single In Line ( SIP 3L flat). Both 3-lead packages are RoHS compliant. 1 V3.10 Nov 1, 2013 SS1072 Unipolar Hall-Effect Digital Switch Glossary of Terms MilliTesla (mT), Gauss RoHS Operating Point (BOP) Release Point (BRP) Units of magnetic flux density: 1mT = 10 Gauss Restriction of Hazardous Substances Magnetic flux density applied on the branded side of the package which turns the output driver ON (VOUT = VDSon) Magnetic flux density applied on the branded side of the package which turns the output driver OFF (VOUT = high) Pin Definitions and Descriptions SOT Pin № SIP Pin № Name Type Function 1 2 3 VDD OUT GND Supply Output Ground Supply Voltage pin Open Drain Output pin Ground pin 1 3 2 Absolute Maximum Ratings Parameter Supply Voltage Supply Current Output Voltage Output Current Storage Temperature Range Operating Temperature Range Temperature Suffix “E” Temperature Suffix “K” Temperature Suffix “L” Symbol VDD IDD VOUT IOUT TS Symbol TA TA TA Value 28 50 28 50 -65 to 170 Value -40 to 85 -40 to125 -40 to 150 Units V mA V mA °C Units °C °C °C Exceeding the absolute maximum ratings may cause permanent damage.
