HAL525

switching offset compensation at typically 115 kHz
operates from 3.8 V to 24 V supply voltage
operates with static magnetic fields and dynamic magnetic fields up to 10 kHz
overvoltage protection at all pins
reverse-voltage protection at VDD-pin
magnetic characteristics are robust against mechanical stress effects
short-circuit protected open-drain output by thermal shut down
constant switching points over a wide supply voltage range
the decrease of magnetic flux density caused by rising temperature in the sensor system is compensated by a built-in negative temperature coefficient
of the magnetic characteristics
ideal sensor for window lifter, ignition timing, and revolution counting in extreme automotive and industrial environments
EMC corresponding to DIN 40839

The HAL525 is a latching sensor (see Fig. 41).

The output turns low with the magnetic south pole on the branded side of the package and turns high with the magnetic north pole on the branded side. The output of HAL525 does not change if the magnetic field is removed. For changing the output state, the opposite magnetic field polarity must be applied.For correct functioning in the application, the sensor requires both magnetic polarities (north and south) on the branded side of the package.
