1 / 2 page HAL 1xy April/2009 PRODUCT INFORMATION HAL ® 1xy Low-Cost Hall-Effect Sensor Family PRODUCT INFORMATION The HAL 1xy Hall switch family is designed for home appliances and industrial applica- tions. The sensors are produced in CMOS technology and include a temperature-com- pensated Hall plate with active offset com- pensation, a comparator, and an open-drain output transistor. The comparator compares the actual mag- netic flux through the Hall plate (Hall volt- age) with the fixed reference values (switch- ing points). Accordingly, the output transistor is switched on or off. The active offset compensation leads to magnetic parameters which are robust against mechanical stress effects. In addi- tion, the magnetic characteristics are con- stant in the full supply voltage and tempera- ture range. The HAL 1xy family is available in the SOT89B SMD package and in the leaded TO92UA package. Features V Temperature ranges – C (Commercial, TJ = 0 °C to +85 °C) – I (Industrial, TJ = 20 °C to +125 °C) V Operates from 3.8 V to 24 V supply volt- age V Operates with static magnetic fields and dynamic magnetic fields up to 10 kHz V Overvoltage protection at all pins V Reverse-voltage protection at VDD pin V Magnetic characteristics are robust against mechanical stress effects V Short-circuit protected open-drain out- put by thermal shut down V Constant switching points over a wide supply voltage and temperature range V The decrease of magnetic flux density caused by rising temperature in the sen- sor system is compensated by a built-in negative temperature coefficient of the magnetic characteristics V High temperature stability for home appliances and industrial applications V High ESD rating Major Applications The HAL 1xy is the optimal system solution for application fields, such as: V White goods – selector switches – door lock detection – RPM detection V Power tools – speed control – direction switch V Home automation – garage openers – door openers V Industrial applications – Endposition detection – RPM measurement of motors – Brushless DC motors – RPM measurements in flow meters – Replacement of micro switches |
