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
capable of sinking up to 300 mA continuously. Increased current
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
碌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擄C to +85擄C, and is supplied in an environmentally rugged, four-pin
miniature plastic SIP. Consult the factory for alternate packaging and
custom magnetic requirements.
