UGN3177, UGN3175, (UGN3175 / UGN3177) HALL-EFFECT LATCHES
3175 AND 3177 HALL-EFFECT LATCHES These Hall-effect latches are temperature-stable and stress-resistant sensors especially suited for electronic commutation in brushless dc motors using multipole ring magnets.
Each device includes a voltage regulator, quadratic Hall voltage generator, temperature compensation circuit, signal amplifier, Schmitt trigger, and an open-collector output on a single silicon chip.
The on-board regulator permits operation with supply voltages of 4.5 volts to 18 volts.
