HIGH SENSITIVE HALL-EFFECT SWITCH INTEGRATED CIRCUITS

Product Description

These Hall-effect switches are monolithic integrated circuits with tighter magnetic specifications and high sensitivity, designed to operate continuously over extended temperatures to ***0°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. Each device includes a voltage regulator for operation with supply voltages of 4.5 to *4 volts, reverse battery protection diode, quadratic Hall-voltage generator, temperature compensation circuitry, small-signal amplifier, Schmitt trigger, and an open-collector output to sink up to *5 mA. With suitable output pull up, they can be used with bipolar or CMOS logic circuits.
