SINGLE OUTPUT HALL EFFECT LATCH
Description
Pin Assignments
ATS177 is an integrated Hall-Effect latch 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 provides a temperature compensated
supply voltage for internal circuits and allows a wide operating
supply range.

Applications
When the magnetic flux density (B) is larger than operate
point (Bop), output is switched on (DO pin is pulled low). The
output state is held on until a magnetic flux density reversal
falls below Brp. When B is less than Brp, the output is
switched off.
