Dual-coil Brush-less DC Motor
Dual-coil Brush-less DC Fan
Revolution Counting
Speed Measurement
ATS276/277 are integrated Hall sensors with output
drivers, mainly designed for electronic commutation
of brush-less DC Fan. This IC internally includes
the regulator, protecting diode, Hall plate, amplifier,
comparator, and a pair of complementary
open-collector outputs
(DO, DOB).
While the magnetic flux density
(B)
is larger than
operate point
(Bop), DO
will turn on (low), and
meanwhile
DOB
will turn off (high). Each output is
latched until
B
is lower than release point
(Brp),
and then
DO、DOB
transfer each state.
For DC fan application, sometimes need to test
power reverse connection condition. Internal diode
only protects chip-side but not for coil-side. If
necessary, add one external diode to block the
reverse current from coil-side.
