Block Diagram of the TLE4998P8(D) with the PWM interface
Functional Description
The linear Hall IC TLE4998P8(D) has been designed specifically to meet the requirements of highly accurate angle
and position detection.
The sensor provides a digital PWM signal, which is well suited for direct decoding by any unit measuring a duty
cycle of a rectangular signal (usually a timer/capture unit in a microcontroller).
The output stage is an open-drain driver pulling the output pin to low only. Therefore, the high level needs to be
obtained by an external pull-up resistor. This output type has the advantage that the receiver may use an even
lower supply voltage (e.g. 3.3 V). In this case the pull-up resistor must be connected to the given receiver supply.
The IC is produced in BiCMOS technology with high voltage capability and it also has reverse-polarity protection.
Digital signal processing using a 16-bit DSP architecture together with digital temperature and stress
compensation guarantees excellent stability over the whole temperature range and life time.
The PWM output frequency can be selected within the range of 122 Hz up to 1953 Hz.

Principle of Operation
A magnetic flux is measured by a Hall-effect cell
The output signal from the Hall-effect cell is converted from analog to digital signals
The chopped Hall-effect cell and continuous-time A/D conversion ensure a very low and stable magnetic offset
A programmable low-pass filter to reduce noise
The temperature is measured and A/D converted
Temperature compensation is done digitally using a second-order function
Digital processing of the output value is based on zero field and sensitivity value
The output value range can be clamped by digital limiters
The final output value is transferred in a rectangular, periodic signal with varying duty cycle (Pulse Width
Modulation)
The duty cycle is proportional to the 12-bit output value
2.4
Transfer Functions
The examples in Figure 2-2 show how different magnetic field ranges can be mapped to the desired output value
ranges.

•
Polarity Mode:
– Bipolar: Magnetic fields can be measured in both orientations. The limit points do not necessarily have to
be symmetrical around the zero field point
– Unipolar: Only north- or south-oriented magnetic fields are measured
Inversion: Both gain can be set to positive values, negative values or positive/negative values.

1) For limited time of 96 h. Depends on customer temperature lifetime cycle. Please ask Infineon for support.
2) Higher voltage stress than absolute maximum rating, e.g. 150% in latch-up tests is not applicable. In such cases, Rseries
≥100 Ω for current limitation is required.
3) Max 1h, in operating temperature range.
4) IDD can exceed 10 mA when the voltage on OUT is pulled below -1 V (-5 V at room temperature).
5) VDD = 5 V, open drain permanent low, for max. 10 minutes
Attention: Stresses above those listed under “Absolute Maximum Ratings” may cause permanent
damage to the device. 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.

TLE4998P8(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 TLE4998P8(D) type):
•
•
•
VDD = 5 V
IDD = 8 mA
∆T= 150[K/W] x (5 [V] x 0.008 [A] + 0 [VA]) = 6 K per silicon
For molded sensors, the calculation with RthJC is more adequate.

The TLE4998P8(D) has several configurable parameters which are stored in the EEPROM. These parameters
affect the internal data processing and compensation and the output protocol. This chapter gives an overview of
the parameters. A detailed description of all the parameters and the programming procedure is given in the
TLE4998 User’s Manual.

1) DY = PWM duty cycle
2) Subject to oscillator variation ±20%.
3) Relative range to Infineon temperature pre-calibration, the maximum adjustable range is limited by the register-size and
depends on specific pre-calibrated TL setting, full adjustable range: -2441 to +5355 ppm/°C.
4) Relative range to Infineon temperature pre-calibration, the maximum adjustable range is limited by the register-size and
depends on specific pre-calibrated TQ setting, full adjustable range: -15 to +15 ppm/°C2.

Error Detection
Different error cases can be detected by the On-Board-Diagnostics (OBD) and reported to the micro controller.
The OBD can only be used with the clamping functionality enabled.

EEPROM Error Correction
The parity method is able to correct a single bit in the EEPROM line. One other single bit error in another EEPROM
line can also be detected, but not corrected. In case there is an incorrectable EEPROM failure, the open drain
stage is disabled and permanently kept in off state (high ohmic/sensor defect).
