HAL® 710/730 Hall-Effect Sensors with Direction Detection
The HAL 710/730 Hall switch family is produced in CMOS technology. The sensors include two independent temperature-compensated Hall plates each equipped with active offset compensation and a comparator. The sensors provide two open-drain outputs – one for “count” and one for “direction” detection.
The comparator compares the actual magnetic flux through the Hall plates (Hall volt-age) with the fixed reference values (switching points). The first comparator directly switches the count output. The phase shift between both comparators determine the state of the direction output.
The active offset compensation leads to magnetic parameters which are robust against mechanical stress effects. In addition, the magnetic characteristics are constant over the full supply voltage and temperature range.
The sensors are designed for industrial and automotive applications and operate with supply voltages from 3.8 V to 24 V in the ambient temperature range from −40°C up to 125°C.
The HAL 710/730 family is available in the SMD package SOT-89B-3.
