FS177

Low Voltage Hall Effect Latch

Technology

General Description

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.
