The sensor provides a ratiometric analog output voltage, which is ideally suited to Analog-to-Digital (A/D) conversion with the supply voltage as a reference. The IC is produced in BiCMOS technology with high voltage capability and also provides reverse polarity protection. Digital signal processing using a 16-bit DSP architecture together with digital temperature and analog stress compensation guarantees excellent stability over the whole temperature range and life time.

This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Furthermore, only single error cases are assumed. More than one stress/error case may also damage the device. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. During absolute maximum rating overload conditions the voltage on VDD pins with respect to ground (VSS) must not exceed the values defined by the absolute maximum ratings. Lifetime statements are an anticipation based on an extrapolation of Infineon’s qualification test results. The actual lifetime of a component depends on its form of application and type of use etc. and may deviate from such statement. The lifetime statement shall in no event extend the agreed warranty period.

Data Sheet 10 Revision 1.1, 2018-01 TLE4997A8(D) Electrical, Thermal and Magnetic Parameters Ratiometry The linear Hall sensor works like a potentiometer. The output voltage is proportional to the supply voltage. The division factor depends on the magnetic field strength. This behavior is called “ratiometric”’. The supply voltage VDD should be used as the reference for the A/D Converter of the micro controller. In this case, variations of VDD are compensated.The ratiometry error is defined as follows: ⎛V (V ) V ( 5V ) ⎞ ⎟⎟ × 100 % E RAT = ⎜⎜ OUT DD − OUT 5 V V DD ⎝ ⎠ (5.1) The ratiometry error band displays as a “Butterfly Curve”. % ERAT 1 0.75 0.5 0.25 0 -0.25 -0.5 -0.75 -1 4 5 6 7 VDD Figure 5-1 V Ratiometry Error Band Note: Take care of possible voltage drops on the VDD and VOUT line degrading the result. Ideally, both values are acquired and their ratio is calculated to gain the highest accuracy. This method should be used especially during calibration. Data Sheet 11 Revision 1.1, 2018-01 TLE4997A8(D) Electrical, Thermal and Magnetic Parameters Calculation of the Junction Temperature The internal power dissipation PTOT of the sensor increases the chip junction temperature above the ambient temperature. The power multiplied by the total thermal resistance RthJA (Junction to Ambient) added to TA leads to the final junction temperature. RthJA is the sum of the addition of the two components, Junction to Case and Case to Ambient. RthJA = RthJC + RthCA TJ = TA + ∆T = RthJA x PTOT = RthJA x ( VDD x IDD + VOUT x IOUT ); IDD, IOUT > 0, if direction is into IC Example (assuming no load on VOUT and TLE4997A8 type): • • • VDD = 5 V IDD = 8 mA ∆T= 150[K/W] x (5 [V] x 0.008 [A] + 0 [VA]) = 6 K For molded sensors, the calculation with RthJC is more applicable. 5.2 Magnetic Charactheristics Table 5-2 Magnetic Characteristics Parameter Sensitivity Symbol 1) S Values Unit Note / Test Condition Min.
