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

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)
