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 of safety features to support Safety Integrity Level (SIL). Sensors with this
performance are identified by the following logo:
Figure 5 PRO-SILTM Logo
Safety features are:
⢠Test vectors switchable to ADC input
⢠Inversion or combination of filter input streams
⢠Data transmission check via 8-bit Cyclic Redundancy Check (CRC)
⢠Self-test routines
⢠Two independent active interfaces possible
⢠Overvoltage and undervoltage detection
Disclaimer
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 high efficiency Safety System.
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)
