TLE5012 Datasheet, PDF (13/57 Pages) Infineon Technologies AG – GMR-Based Angular Sensor for Rotor Position Sensing

TLE5012
Functional Description
2.5.4 Digital Signal Processing Unit
The Digital Signal Processing Unit (DSPU) contains the:
• Capture Compare Unit (CCU), which is used to generate the PWM signal
• COordinate Rotation DIgital Computer (CORDIC), which contains the trigonometric function for angle
calculation
• Fuses, which contain the calibration parameters
2.5.5 Interfaces
Different Interfaces can be selected:
• SSC Interface
• PWM
• Incremental Interface
• Hall Switch Mode
2.5.6 Safety Features
The TLE5012 offers a multiplicity on safety features to support Safety Integrity Level (SIL). Sensors with this
performance are identified by the following logo:
Figure 5 PRO-SIL^TM Logo
Safety features are:
• Test vectors switchable to ADC- input
• Inversion or combination of filter input streams
• Data transmission check via 8bit Cyclic Redundancy Check (CRC)
• Self test routines
• Two independent active interfaces possible
• Overvoltage and undervoltage detection

PRO-SIL™ is a Registered Trademark of Infineon Technologies AG.
The PRO-SIL™ Trademark designates Infineon products which contain SIL Supporting Features.
SIL Supporting Features are intended to support the overall System Design to reach the desired SIL (according
to IEC61508) or A-SIL (according to ISO26262) level for the Safety System with high efficiency.
SIL respectively A-SIL certification for such a System has to be reached on system level by the System
Responsible at an accredited Certification Authority.
SIL stands for Safety Integrity Level (according to IEC 61508)
A-SIL stands for Automotive-Safety Integrity Level (according to ISO 26262)
