AH3601

AH3601 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, They combine 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, signal amplifier, 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.
