These hall-effect latches are temperature-stable and stress-resistant sensors especially suited for electroniccommutation in brushless DC motors using multipole ring magnets. Each device includes a voltage regulator, quadratic hall voltage generator, temperature compensation circuit, signal amplifier, schmitt trigger, and anopen-collector output on a single silicon chip. The on-board regulator permits operation with supply voltages of 4.5volts to 24 volts. The switch output can sink 25 ma. With suitable output pull up, they can be used directly withbipolar or MOS logic circuits.
