Hall-effect switch integrated circuits
These hall-effect switches are monolithic integrated circuits with tighter magnetic specifications and highsensitivity, designed to operate continuously over extended temperatures to +150° And are more stable withc, both temperature and supply voltage changes. The unipolar switching characteristic makes these devices ideal foruse with a simple bar or rod magnet.Each device includes a voltage regulator for operation with supply voltages of 4.5 to 24 volts, reverse batteryprotection diode, quadratic hall-voltage generator, 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 usedwith bipolar or CMOS logic circuits.
