FEELING TECHNOLOGY Single Hall Effect Latch FS3144 Features Wide operating voltage range: 3.0V to 28V Maximum output sink current 50mA Open-Collector pre-driver Power reverse polarity protection Available in SIP-3L package Halogen Free General Description The FS3144 is an integrated Hall effect latched 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 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.
