4. Type Description
4.1. HAL525
The HAL525 is a latching sensor (see Fig. 4–1).
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 out-
put 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.
Magnetic Features:
– switching type: latching
– low sensitivity
– typical B
ON
: 14 mT at room temperature
– typical B
OFF
:
14 mT at room temperature
– operates with static magnetic fields and dynamic
magnetic fields up to 10 kHz
– typical temperature coefficient of magnetic switching
points is
2000 ppm/K
Applications
The HAL525 is the optimal sensor for applications with
alternating magnetic signals such as:
– multipole magnet applications,
– rotating speed measurement,
– commutation of brushless DC motors, and
– window lifter.
