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 These Hall-effect switches are monolithic integrated circuits with tighter magnetic specifications, designed to operate continuously over extended temperatures to +150℃, and are more stable with both temperature and supply voltage changes. If a magnetic flux density larger than threshold Bop, Output is turned on (low). The output state is held until a magnetic flux density reversal falls below BRP, causing Output to be turned off (high). Thanks to its wide operating voltage range and extended choice of temperature range, it is quite suitable for use in DC motor applications. 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. 1 V2.10 May 1, 2012 SS539 Bipolar Hall-Effect Position Sensor 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 Table 1: Pin definitions and descriptions Absolute Maximum Ratings Parameter Symbol Supply Voltage VDD Supply Current IDD Output Voltage VOUT Output Current IOUT Storage Temperature Range TS Table 2: Absolute maximum ratings Operating Temperature Range Temperature Suffix “E” Temperature Suffix “K” Temperature Suffix “L” Symbol TA TA TA Value 28 50 28 50 -65 to 170 Units V mA V mA °C Value -40 to 85 -40 to125 -40 to 150 Units °C °C °C Exceeding the absolute maximum ratings may cause permanent damage.
