COMPLEMENTARY-OUTPUT HALL-EFFECT LATCH
Type UGN3275K latching Hall-effect sensors are bipolar integrated 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.
