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,
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.
