ATS177

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.
