ATS276
COMPLEMENTARY OUTPUT HALL EFFECT LATCH
General Description
Features
ATS276 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,

On-Chip Hall Sensor with Two Different Sensitivity and
Hysteresis Settings for ATS276
3.5V to 20V Operating Voltage
400mA (avg.) Output Sink Current
Built-in Protecting Diode Only for Chip Reverse Power

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.
SIP-4L: Available in “Green” Molding Compound
(No Br, Sb)
Lead Free Finish/RoHS Compliant (Note 1)
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.

Notes:
6. The Vz may vary with the inductance/resistance of DC Fan. In order to reduce the risk of dynamic operation, the capacitor/ resistor is
recommended to add below the DO/DOB as Application Circuit (see General Description on page 1).
