FS177  Low Voltage Hall Effect Latch
General Description
Download
 The FS177 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.


Features
˙Wide operating voltage range: 3.0V to 20V
˙Maximum output sink current 25mA
˙Open-Collector pre-driver
˙Reverse polarity protection
˙Package : TO-92SP-3
