How Does it Work?
A Hall IC switch is OFF with no magnetic field and ON in the presence of a magnetic field, as seen in Figure
1. The Earths field will not operate a Hall IC Switch, but a common refrigerator magnet will provide sufficient
strength to actuate the sensor.
Figure 1, How it Works
No magnetic field = OFF South magnetic pole = ON
But How Much Do They Cost?
The cost of a Hall IC depends on the application. Automotive Hall ICs may cost $0.35 to $1.50 or more, while
Hall ICs for Industrial and Consumer applications, such as appliances, game machines, industrial manufactur-
ing, instrumentation, telecom and computers, cost $0.20 or less.
Automotive chip costs are higher because of the unique requirements for shorted loads, reverse battery, double
battery voltage, load dump, 100% test at three temperatures and temperature operation up to 200
o
C. Devices
that do not meet the stringent automotive specifications are more than adequate for other environments, such as
in industrial and consumer products. Melexis products are created primarily to meet automotive specifications,
with off-spec parts sold at a lower price. The cost directly reflects how well the part performs versus the sever-
ity of the operating environment.
