Clamping (not enabled in -E6782 version)
The clamping function is useful to split the output voltage range into operating range and
error ranges.
If the magnetic field is outside the selected measurement range, the output voltage
V
out
is limited to the clamping values.
Therefore an output voltage in the error range indicates a wire breakage (see
Open
Circuit (OBD parameters)
,
Table 12
) or a short circuit.
The clamping function is enabled, when the clamp bit is set.
The following figure shows how the magnetic field range between
B
min
and
B
max
is
mapped to voltages between 0.5 V and 4.5 V.
If it is not necessary to signal errors, the clamping should be disabled. In this case the
maximum output voltage range between 0.3 V and 4.7 V can be used.
