low-cost bipolar digital Hall-effect IC sensor
Bipolar magnetics - Sinking output - High output current capability - High speed capability - Reverse polarity protection - Small through-hole and surface mount (SOT-23 and SOT-89B) packages - Tape and reel available Integrated circuitry provides enhanced temperature stability in a robust design. Thermally balanced integrated circuit over full temperature range. Built-in regulator provides stable operation over supply voltage range. Open-collector sinking output voltage easily interfaces with wide variety of electronic circuits. Internal circuitry prevents sensor damage in case supply voltage polarity is accidentally reversed. Potential applications include speed and RPM sensing, brushless dc motor commutation, motor and fan control, magnetic encoding, disc speed, tape rotation, and flow-rate sensing
