ULTRA-SENSITIVE BIPOLAR HALL-EFFECT SWITCHES
The Hall-effect switch is designed for magnetic actuation using a bipolar magnetic field, i.e., a north-south
alternating field, and they are designed to operate continuously over extended temperatures to +100°C, Theycombine extreme magnetic sensitivity with excellent stability over varying temperature and supply voltage. The
high sensitivity permits their use with multi-pole ring magnets over relatively large distances.
Each device includes a voltage regulator, quadratic Hal voltage generator, temperature stability circuit, signalamplifier, Schmitt trigger, and open-collector output on a single silicon chip. The on-board regulator permits
operation with supply voltages of 2.5 to 18 V. The switch output can sink up to 15 mA. With suitable output pull up,
they can be used directly with bipolar or MOS logic circuits.
