TLE5014SP16 E0002014SP02 SP004531446PG-TDSO-16SSC Interface, single die
The internal blocks of the TLE5014SP16 E0002 are supplied from several voltage regulators:
•GMR Voltage Regulator, VRS
•Analog Voltage Regulator, VRA
•Digital Voltage Regulator, VRD
These regulators are directly connected to the supply voltage VDD.
Oscillator and PLL (Clock)
The digital clock of the TLE5014SP16 E0002 is given by the Phase-Locked Loop (PLL), which is fed by an
internal oscillator.
SD-ADC
The Sigma-Delta Analog-Digital-Converters (SD-ADC) transform the analog GMR voltages and temperature
voltage into the digital domain.
Digital Signal Processing Unit ISM_ALG
The Digital Signal Processing Unit ISM_ALG contains the:
•Intelligent State Machine (ISM), which does error compensation of offset, offset temperature drift,
amplitude synchronicity and orthogonality of the raw signals from the GMR bridges.
•COordinate Rotation DIgital Computer (CORDIC), which contains the trigonometric function for angle
calculation

GMR-based Angle Sensor
Functional Description
Digital Signal Processing Unit ISM_SAF
The Digital Signal Processing Unit ISM_SAF performs the internal safety mechanism and plausibility checks.
Furthermore, a second CORDIC algorithm is implemented in a diverse way as in the ISM_ALG. This is for cross
checking the angle calculation
Interface
The Interface block is used to generate the SSC signals
Angle Compare
This digital block compares the angle value calculated by ISM_ALG and ISM_SAF. In case they are not identical,
an error is indicated in the transmitted protocol.
EEPROM
The EEPROM contains the configuration and calibration parameters. A part of the EEPROM can be accessed by
the customer for application specific configuration of the device. Programming of the EEPROM is achieved
with the SSC interface. Programming mode can be accessed directly after power-up of the IC.
1.3Sensing Principle
The Giant Magneto Resistance (GMR) sensor is implemented using vertical integration. This means that the
GMR-sensitive areas are integrated above the logic part of the TLE5014SP16 E0002 device. These GMR
elements change their resistance depending on the direction of the magnetic field.
Four individual GMR elements are connected to one Wheatstone sensor bridge. These GMR elements sense
one of two components of the applied magnetic field:
•X component, V
•Y component, V
With this full-bridge structure the maximum GMR signal is available and temperature effects cancel out each
other.

Functional Description
Figure 1-2 Sensitive bridges of the GMR sensor (not to scale)
In Figure 1-2 the arrows in the resistors represent the magnetic direction which is fixed in the reference layer.
If the external magnetic field is parallel to the direction of the Reference Layer, the resistance is minimal. If
they are anti-parallel, resistance is maximal.
The output signal of each bridge is only unambiguous over 180° between two maxima. Therefore two bridges
are oriented orthogonally to each other to measure 360°.
With the trigonometric function ARCTAN2, the true 360° angle value is calculated out of the raw X and Y signals
from the sensor bridges.

Application Circuits
2Application Circuits
The application circuit in this chapter shows the communication possibilities of the TLE5014SP16 E0002. To
improve robustness against electro-magnetic disturbances, a capacitor of 100nF on the supply is
recommended. This capacitor shall be placed as close as possible to the corresponding sensor pins. The load
capacitor C
but the driver is switched off once reaching the HIGH state. Therefore, a pull-up resistor is recommended to
maintain a stable HIGH level.
In case of a high speed communication, an additional serial resistor in the range of 140Ω can be implemented
in the DATA, SCK and CSQ line to avoid reflections and enhance communication reliability. In this case the user
is responsible to verify that the intended communication speed can be reached in his specific setup.

Magnetic Field Range
The operating range of the magnetic field describes the field values where the performance of the sensor,
especially the accuracy, is as specified in Table 3-11 and Table 3-12. This value is valid for a NdFeB magnet
with a Tc of -1300ppm/K. In case a different magnet is used, the individual Tc of this magnet has to be
considered and ensured that the limits are not exceeded. The allowed magnetic field range is given in
