ATS277H
COMPLEMENTARY OUTPUT HALL EFFECT LATCH
General Description
Features
ATS277H 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.
SIP-4L: Available in “Green” Molding Compound
(No Br, Sb)
Lead Free Finish/ RoHS Compliant (Note 1)
