General Description
AH276 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
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.
