AH276Q

COMPLEMENTARY OUTPUT HALL EFFECT LATCH

General Description

Features

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,

•

On-chip Hall sensor with two different sensitivity and

hysteresis settings for AH276

Built-in protecting diode only for chip reverse power

connecting

-20°C to 85°C operating temperature

Lead Free Package: SIP-4L

SIP-4L: Available in “Green” Molding Compound

(No Br, Sb)

Lead Free Finish/RoHS Compliant (Note 1)

amplifier, comparator, and

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.
