Programmable Linear Hall Effect Sensor
1. Introduction
The
HAL 800
is an universal magnetic field sensor with
a linear output based on the Hall effect. The IC is
designed and produced in sub-micron CMOS technol-
ogy and can be used for angle or distance measure-
ments if combined with a rotating or moving magnet.
The major characteristics like magnetic field range,
sensitivity, output quiescent voltage (output voltage at
B = 0 mT), and output voltage range are programma-
ble in a non-volatile memory. The sensor has a ratio-
metric output characteristic, which means that the out-
put voltage is proportional to the magnetic flux and the
supply voltage.
The
HAL 800
features a temperature compensated
Hall plate with choppered offset compensation, an A/D
converter, digital signal processing, a D/A converter
with output driver, an EEPROM memory with redun-
dancy and lock function for the calibration data, a serial
interface for programming the EEPROM, and protec-
tion devices at all pins. The internal digital signal pro-
cessing is of great benefit because analog offsets,
temperature shifts, and mechanical stress do not
degrade the sensor accuracy.
The
HAL 800
is programmable by modulating the sup-
ply voltage. No additional programming pin is needed.
The easy programmability allows a 2-point calibration
by adjusting the output voltage directly to the input sig-
nal (like mechanical angle, distance or current). An
individual adjustment of each sensor during the cus-
tomers manufacturing process is possible. With this
calibration procedure the tolerances of the sensor, the
magnet, and the mechanical positioning can be com-
pensated in the final assembly.
In addition, the temperature compensation of the Hall
IC can be fit to all common magnetic materials by pro-
gramming first and second order temperature coeffi-
cients of the Hall sensor sensitivity. This enables an
operation over the full temperature range with high
accuracy.
The calculation of the individual sensor characteristics
and the programming of the EEPROM memory can
easily be done with a PC and the application kit from
Micronas. The
HAL 800
eases logistic because its
characteristics can be programmed in a wide range.
Therefore, one Hall IC type can be used for various
applications.
The sensor is designed for hostile industrial and auto-
motive applications and operates with typically 5 V
supply voltage in the ambient temperature range from
40 °C up to 150 °C.
The
HAL 800
is available in the very small leaded
package TO-92UT.

tics, the
