/circle6 Wide operating voltage range: 3.0V to 28V /circle6 Maximum output sink current 50mA /circle6 Open-Collector pre-driver /circle6 Power reverse polarity protection /circle6 Available in SIP-3L package General Description The FS41 is an integrated Hall effect latched sensor designed for electronic commutation of brush-less DC motor applications. The device includes an on-chip Hall v oltage generator for magnetic sensing, a comparator that amplifies the Hall voltage, and a Schmitt trigger t o provide switching hysteresis for noise rejection, and open-collector output. An internal bandgap regulator is used to provide temperature compensated supply voltage for internal circuits and allows a wide operating supply range. A north pole of sufficient strength will turn the output ON. In the absence of a magnetic field, the output is OFF. Block Diagram Figure.1 Pb Free Vdd Regulator Hall Sensor Gnd Output
