General Description
PC177 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.If a magnetic flux density larger than threshold Bop, DO is turnedon (low). The output state is held until a magnetic flux density
reversal falls below Brp causing DO to be turned off (high).
Applications
• Brush-less DC Motor
• Brush-less DC Fan
• Revolution counting
• Speed measurement
