Hall Effect Sensor
Description
- Designed for electronic commutation of brush-less DC motor applications
- Wide operating voltage range
- 5mA maximum sinking output current
- RoHS Compliant
The Hall Effect Sensor is an integrated Hall effect latched sensor designed for electronic commutation of brush-less DC motor applications. The device includes an on-chip Hall voltage generator for magnetic sensing, a comparator that amplifies the Hall voltage, and a schmitt trigger to provide switching hysteresis for noise rejection, and open-collector output. An internal bandgap regulator is used to provide temperature compensated supply voltage for internal circuits and allows a wide operating supply range.
If a magnetic flux density larger than threshold Bop, DO is turned on (low). The output state is held until a magnetic flux density reversal falls below Brp causing DO to be turned off (high).
Features:
- 3.5V to 20V DC operation voltage
- Temperature compensation
- Wide operating voltage range
- Open-Collector pre-driver
- 25mA maximum sinking output current
- Reverse polarity protection
- Lead Free Package: SIP-3L
Applications:
- Brushless DC Motor
- Brushless DC Fan
- Revolution counting
- Speed measurement

Handy sensor for triggering based off magnetic field. Great price and easy to use.
Capteur pratique pour le déclenchement basé sur un champ magnétique. Très bon prix et facile à utiliser.
Great little sensors for the price you pay.
Grands petits capteurs pour le prix que vous payez.
Important to note with this sensor is that depending on which pole of the magnet you use to trip this, you will get different results. Not sure if that how all hall-effect sensors are but just as a note. Otherwise, works fairly well and are tiny enough to use wherever is needed. Price is right too!
