DUAL-OUTPUT
HALL-EFFECT SWITCH
Type UGN3235K Hall-effect sensors are bipolar integrated circuits
designed for commutation of brushless dc motors, and other rotary
encoding applications using multi-pole ring magnets. The device
features two outputs which are independently activated by magnetic
fields of opposite polarity.
Each sensor IC includes a Hall voltage generator, two Schmitt
triggers, a voltage regulator, output transistors, and on-board reverse
polarity protection. The regulator enables these devices to operate
from voltages ranging between 4.5 V and 24 V. On-chip compensation
circuitry stabilizes the switch points over temperature.
Each open-collector output is independently operated by the
proper amount and polarity of incident magnetic flux. Output 1 re-
sponds only to the positive flux from the south pole of a magnet,
Output 2 to the negative flux from the north pole of a magnet. When
the sensor experiences the field of a south magnetic pole greater than
the maximum operate point of Output 1, that output switches to the
LOW state and Output 2 is unaffected. When the incident flux falls

the HIGH state and Output 2 remains unchanged.
Output 2 independently responds in the same manner to the
negative flux from the north magnetic pole of a magnet. Figure 1
shows a zone in the region of 0 G, tH, where both outputs are in the
HIGH or OFF state. This constitutes a delay that is independent of
rate of change of the incident magnetic field and ensures that both
outputs are never ON simultaneously. This is an essential feature for
driving brushless dc motors with a minimum of reactive transient
currents.
The UGN3235K is supplied in a four-pin plastic single in-line
package (SIP).

All Hall effect integrated circuits are susceptible to mechanical stress effects. Caution
should be exercised to minimize the application of stress to the leads or the epoxy
package. Use of epoxy glue is recommended. Other types may deform the epoxy
package.
To prevent permanent damage to the Hall cell, heat-sink the leads during hand
soldering. Recommended maximum conditions for wave soldering are shown in the
graph above.
