TLE5011
Functional Description
2.5.6 Safety Features
The TLE5011 has a multiplicity on safety features to support Safety Integrity Level (SIL). Sensors meeting this
performance standard are identified by Infineon with the following logo:
Figure 5 PRO SIL Logo
Safety features are:
• Angle test (generated via test voltages feeding the ADC).
• Crossed signal paths (switchable for comparison)
• Invertable ADC bitstreams
• Overvoltage and undervoltage detection of internal and external voltages
• V_DD-off and GND-off to detect supply malfunctions
• Frame counter and synchronisation counter
• Separate bandgap-reference voltages for regulators and comparators
• CRC-protected SSC protocol
• Locked configuration registers

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 Respon-
sible 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)
