Type UGN5275K latching Hall-effect sensors are bipolar integrated
circuits designed for electronic commutation of brushless dc motors.
They feature open-collector complementary power outputs that are
ratings, complementary outputs, and sensitive switching points that are
stable over temperature and time ideally suit these devices for mini-
mum-component brushless dc motor designs.
Each sensor IC includes a Hall-voltage generator, an operational
amplifier, a Schmitt trigger, a voltage regulator, and large-area dual
npn-output transistors. The regulator allows the IC to operate with
supply voltages ranging from 4.5 V to 14 V. On-chip compensation
circuitry stabilizes switch point performance over temperature. The
large bipolar junction output transistors are fed by a unique driver
stage, which minimizes power dissipation within the IC. The magnetic
operation of this device is similar to that of the UGN3275K complemen-
tary-output Hall-effect latch.
Output Q of the IC switches to the LOW state when the internal
Hall generator experiences a magnetic field that exceeds the rated
operate point. Output Q switches HIGH within one
μ
s of the Output Q
change of state. When the device is exposed to a sufficient magnetic
field of opposite polarity, Output Q returns to the HIGH state, and
Output Q returns to the LOW state.
The UGN5275K is rated for operation over a temperature range of
-20
°
C to +85
°
C, and is supplied in an environmentally rugged, four-pin
miniature plastic SIP. Consult the factory for alternate packaging and
custom magnetic requirements.
