TLE4990 Programmable Linear Hall Sensor
Functional Description 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 (Vzero) The output voltage with no magnetic field present is called the zero field voltage Vzero. It is programmable within the range of 3% to 19% of VDD (for Bipolar bit = 0) and 40% to 60% of VDD (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. Clamping Option It is possible to reduce the output voltage swing from its original 3%... 97% VDD to a limited swing of 10% ... 90% VDD 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 VDD. Note: The -E6782 version has this feature disabled.

Principle of Operation * * * * * * * * A magnetic flux is measured by a Hall-Effect cell. The Temperature compensation modulates the bias current of the hall cell. The output signal from the Hall-Effect cell is amplified. A zero field voltage is added. The output voltage range can be clamped by limiters. The final output value is amplified and buffered. The output voltage is proportional to the supply voltage (ratiometric behavior). An OBD (On Board Diagnostics) circuit connects the output to VDD or GND in case of errors.

B10% is the magnetic field, at which VOUT = 0.1 x VDD. B90% is the magnetic field, at which VOUT = 0.9 x VDD. VOUT,id = [0.1 + 0.8 x (B - B10%) / (B90% - B10%)] x VDD. Lin = (VOUT / VOUT,id - 1) * 100% for all VOUT between 10% VDD and 90% VDD.
The temperature coefficient of the magnetic sensitivity is the slope of a linear least-square fit through the real curve. For lower sensitivities, the zero voltage drift is dominant (see Table 4). Equivalent to magnetic input noise at 25 C. The equivalent magnetic input noise depends on the selected sensitivity. At highest sensitivity it is typically 25 TRMS, at lowest sensitivity it is typically 50 TRMS at 25 C.

Magnetic Field Ranges
Note: The Range setting is fixed in the -E6782 version. The output signal of the Hall cell is amplified in the pre-amplifier. Eight ranges can be selected by setting the PRE bits. The output voltage range of 3 ... 97% of VDD leads to a swing of 4.7 V at VDD = 5 V. Therefore the product of sensitivity and full scale range is always 4.7 V. Note: Sensitivity x Full Scale range = 4.7 V

Clamping
Note: The Clamping function is not enabled in the -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 Vout 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.

Error Detection
Broken supply lines can be detected by the OBD (On Board Diagnostics) and reported to the Controller. Note: The OBD is only useful when the clamping function is enabled. In the case of interrupted supply lines, the Controller may warn the user. If two sensors are placed in parallel, the output of the remaining working sensor may be still used for an emergency operation.

Calibration and Fusing

Calibration and Fusing
Usually the sensor is calibrated 'End Of Line', when the complete magnetic system is assembled. This compensates all magnetic and mechanical tolerances. Note: The -E6782 version is already programmed completely. The contents of the calibration OTP memory may not be changed furthermore. During the calibration the internal settings are stored in a RAM. When the right values are found, the information has to be stored in an one-time-programmable memory (OTP). This OTP memory consists of cavity fuses. After fusing all bits, setting the MEMLOCK bit closes the memory. This prevents from unwanted memory changes after the calibration Data Transfer Protocol A separate programming specification may be requested. Programming of Sensors with Common Supply Lines In many automotive applications two sensors are used to measure the same parameter. This redundancy allows to continue the operation in an emergency mode. If both sensors use the same power supply lines, they have to be programmed together. Sensor Interface Tool For the calibration of the sensor, a special hardware interface to a PC is required.
