COMPLEMENTARY-OUTPUT
HALL-EFFECT LATCH
Type UGN3275K latching Hall-effect sensors are bipolar inte-
grated circuits designed for electronic commutation of brushless dc
motors. They feature dual complementary outputs. The latches are
typically used to sense matched magnetic flux densities of alternating
polarity from multipole ring magnets.
Each sensor IC includes a Hall voltage generator, operational
amplifier, Schmitt trigger, voltage regulator, and dual bipolar output
transistors. The regulator allows use of the integrated circuit with
supply voltages of 4.5 V to 24 V.
If the Hall cell is exposed to a magnetic flux density greater than
the operate threshold (BOP), OUTPUT goes low (turns on) and
OUTPUT goes high (turns off). The outputs will hold (latch) this state
until magnetic field reversal exposes the Hall cell to a magnetic flux
density below the release threshold (BRP) when OUTPUT will go high
(off) and OUTPUT will go low (on). This state is also latched. Under
any condition one output is on while the other is off. Because the DataShee
operating state switches only with magnetic field reversal, and not
mDeartaeSlyhweeitht4aU.cchoamnge in the strength, these integrated circuits qualify
as true Hall-effect latches.
These complementary-output Hall-effect latches are supplied in a
four-pin plastic SIP, 0.200" (5.08 mm) wide, 0.130" (3.3 mm) high, and
0.060" (1.54 mm) thick.

5. Complementary outputs for 2-phase bifilar-wound, unipolar-driven brushless dc motor control.
* Minimum. Maximum
Latches will not switch on removal of magnetic field; bipolar switches may switch on removal of field but require field reversal
for reliable operation over operating temperature range.
