Introduction
The HAL 700 is a monolithic CMOS Hall-effect sensor consisting of two independent latched switches (see Fig. 3–3) with closely matched magnetic characteristics controlling two independent open-drain outputs. The Hall plates of the two switches are spaced 2.35 mm apart.

FEATUREs
– two independent Hall-switches
– distance of Hall plates: 2.35 mm
– low sensitivity
– typical BON: 14.9 mT at room temperature
– typical BOFF: −14.9 mT at room temperature
– temperature coefficient of −2000 ppm/K in all magnetic characteristics
– switching offset compensation at typically 150 kHz
– operation from 3.8 V to 24 V supply voltage
– operation with static and dynamic magnetic fields up to 10 kHz
– overvoltage protection at all pins
– reverse-voltage protection at VDD-pin
– robustness of magnetic characteristics against mechanical stress
– short-circuit protected open-drain outputs by thermal shutdown
– constant switching points over a wide supply voltage range
– EMC corresponding to DIN 40839

APPLICATIONs
The HAL 700 is the ideal sensor for position-control applications with direction detection and alternating magnetic signals such as:
– multipole magnet applications,
– rotating speed and direction measurement, position tracking (active targets), and
– window lifters.
