1. IntroductionThe HAL 5xy family consists of different Hall switchesproduced in CMOS technology. All sensors include atemperature-compensated Hall plate with active offsetcompensation, a comparator, and an open-drain outputtransistor. The comparator compares the actualmagnetic flux through the Hall plate (Hall voltage) withthe fixed reference values (switching points). Accordingly,the output transistor is switched on or off.The sensors of this family differ in the switching behaviorand the switching points.The active offset compensation leads to constant magneticcharacteristics over supply voltage and temperaturerange. In addition, the magnetic parameters arerobust against mechanical stress effects.The sensors are designed for industrial and automotiveapplications and operate with supply voltages from3.8 V to 24 V in the ambient temperature range from−40 °C up to 150 °C.All sensors are available in the SMD-packageSOT89B-1 and in the leaded versions TO92UA-1 andTO92UA-2.1.1. Features:– switching offset compensation at typically 62 kHz– operates from 3.8 V to 24 V supply voltage– overvoltage protection at all pins– reverse-voltage protection at VDD-pin– magnetic characteristics are robust regardingmechanical stress effects– short-circuit protected open-drain output by thermalshut down– operates with static magnetic fields and dynamicmagnetic fields up to 10 kHz– constant switching points over a wide supply voltagerange– the decrease of magnetic flux density caused by risingtemperature in the sensor system is compensatedby a built-in negative temperature coefficientof the magnetic characteristics– ideal sensor for applications in extreme automotiveand industrial environments– EMC corresponding to ISO 76371.2. Family OverviewThe types differ according to the magnetic flux densityvalues for the magnetic switching points and the temperaturebehavior of the magnetic switching points,and the mode of switching.Latching Sensors:The output turns low with the magnetic south pole onthe branded side of the package and turns high withthe magnetic north pole on the branded side. The outputdoes not change if the magnetic field is removed.For changing the output state, the opposite magneticfield polarity must be applied.Bipolar Switching Sensors:The output turns low with the magnetic south pole onthe branded side of the package and turns high withthe magnetic north pole on the branded side. The outputstate is not defined for all sensors if the magneticfield is removed again. Some sensors will change theoutput state and some sensors will not.
