MH181, Hall-Effect sensor, designed for electronic commutation
of brush-less DC motor
applications. The device includes an on-chip Hall voltage generator for magnetic sensing, a
comparator that amplifies the Hall Voltage, and a Schmitt trigger to provide switching
hysteresis for noise rejection, and open collector output. An internal band gap regulator is used
to provide temperature compensated supply voltage for internal circuits and allows a wide
operating supply range. The device is identical except for magnetic switch points.
The device includes on a single silicon chip a voltage regulator, Hall-voltage generator,
small-signal amplifier, chopper stabilization, Schmitt trigger, open-collector output to sink up
to 25mA. A south pole of sufficient strength will turn the output on. The North Pole is
necessary to turn the output off. An on-board regulator permits operation with supply voltages
of 3.5V to 20 V.
The package type is in a lead Halogen Free
version was verified by third party
organization.
