5 x Hall Effect Switch A3144 TO-92UA package

Description

These Hall-effect switches are monolithic integrated circuits with tighter magnetic specifications, designed to operate continuously over extended temperatures to +150C, 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 24 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 25 mA.

With suitable output pull-ups (for example 10k), they can be used with bipolar or CMOS logic circuits like microcontrollers.
