DESCRIPTION
The IC contains a Hall sensor and the appropriate measurement
system. It detects three levels of upright magnetic field: positive,
near zero and negative. These information are provided at two bi-
nary coded outputs for any logic or uC. The sampling rate is about
10
kHz (typ.) allowing fast movement detection.
In order to attain a very low average current consumption, the IC
does short measurements and holds the result at the output until
the next cycle. During the hold-phase, the IC switches to stand-by
mode with very low power consumption.
With two mode pins it is possible to bring th IC (statically) into a
slow mode, reducing the current consumption furthermore. The
second pin switches into a mode of increased sensitivity, where
lower magnetic fields can be detected.
