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
