HALL EFFECT SENSOR IN INDIA

The US 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 band gap regulator is used to provide temperature compensated supply voltage for internal circuits and allows a wide operating supply range.  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
