TLE4990
Programmable Linear Hall Sensor
Functional Description
Data Sheet
6
V 2.0, 2004-05
General
The linear Hall IC TLE4990 has been designed specifically to meet the demands of
highly accurate rotation and position detection, as well as for current measurement
applications.
The sensor provides a ratiometric analog output voltage which is ideally suited for A/D
conversion with the supply voltage as a reference.
The IC is produced in BiCMOS technology with high voltage capability and also providing
reverse polarity protection.
Zero-field Output Voltage (
V
zero
)
The output voltage with no magnetic field present is called the zero field voltage
V
zero
.
It is programmable within the range of 3% to 19% of
V
DD
(for Bipolar bit = 0) and 40% to
60% of
V
DD
(for Bipolar bit = 1) by 10 ODAC bits with a resolution of 1.0 mV to 1.2 mV.
Magnetic Sensitivity (S)
The magnetic sensitivity is set in two steps: First the "coarse gain" is selected out of 8
values (3 PRE bits). Then the "fine gain" is adjusted by another 10 GDAC bits.
The resulting range of sensitivity extends from 15 mV/mT to 180 mV/mT at the nominal
supply voltage of 5 V. Note that as the sensitivity is ratiometric, it will also depend linearly
on the supply voltage.
The sensitivity of the -E6782 version is programmed during production.
It is calibrated to a value of 20 mV/mT at the nominal supply voltage of 5 V.
Temperature Gain Compensation
The temperature compensation of the sensitivity is programmed during production.
The value of +350 ppm/°C to provides an excellent accuracy for the use of a SmCo
permanent magnet. Stability is achieved by the dynamic offset cancellation technique to
eliminate any spurious mechanical or temperature effects.
The -E6785 version is calibrated to 0 ppm/°C. It can be used e.g. for current
measurement applications.
Clamping Option
It is possible to reduce the output voltage swing from its original 3% ... 97%
V
DD
to a
limited swing of 10% ... 90%
V
DD
by setting the clamping bit. This allows to detect a
broken wire. In this case the output voltage is tied to
≤
6% or
≥
94% of
V
DD
.
The -E6782 version has this feature disabled.
