Hall Effect Sensor - US1881

Rating:

100% of 100

SKU: COM-09312 Brand: Sparkfun

The US1881 is an integrated Hall effect latched sensor. That’s nice but what does it do? Holding a magnet near the sensor will cause the output pin to toggle. This makes for a robust presence sensor. A reed sensor also works nicely, but can be limited by the glass encapsulation and size. A hall effect sensor is much smaller, but can handle less current than a reed switch.

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 24V DC operation voltage
Low current consumption
Temperature compensation
Wide operating voltage range
Open-Collector pre-driver
50mA maximum sinking output current
Reverse polarity protection
Lead Free Package: TO-92
