CYL3503 LINEAR HALL EFFECT Sensors
CYL3503 linear Hall-effect integrated circuit includes a voltage
regulator, Hall-voltage generator, linear amplifier, and emitter-follower
output stage. The output of the ICs changes linearly with the magnetic
flux density of the input.

Principles
The quiescent output voltage (B=0mT) is nominally one-half the supply voltage. When a south
magnetic pole presented to the branded face of the Hall-effect IC, it will drive the output higher than
the quiescent voltage. A north magnetic pole will drive the output below the quiescent output voltage.
In operation, instantaneous and proportional output voltage levels are dependent on magnetic flux
density at the most sensitive area of the device. Greatest sensitivity is obtained with a supply
voltage of 6V, but at the cost of increased supply current and a slight loss of output symmetry. The
IC’ output is usually capacitively coupled to an amplifier that boosts the output above the millivolt
level.

Note:
Mechanical stress should be lessened as far as possible in the process of assembly.
The soldering temperature at the leads should be less than 260°C with 5 seconds. If N pole is
approaching Hall-effect ICs from the back side of the package, output voltage will increase, S pole
is approaching ICs from the back side, output voltage will reduce; and if from the branded side of
the package, the output situation is just to the contrary.
