Introduction
The HAL700 and the HAL740 are monolithic CMOS Hall-effect sensors consisting of two independent switches 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
– 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 shut down
– constant switching points over a wide supply voltage range
– EMC corresponding to ISO 7637
