Protection Functions

The device provides embedded protective functions. Integrated protection functions are designed to prevent IC

destruction under fault conditions described in this Data Sheet. Fault conditions are considered as “outside”

normal operating range. Protection functions are not designed for continuous repetitive operation.

There is an overload and overtemperature protection implemented in the SPIDER - TLE7232GS. The behavior of

the protective functions can be set-up via SPI. Following figure gives an overview about the protective functions.
