4.2
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 over load and over temperature protection implemented in the SPIDER -
TLE7232G. The behavior of the protective functions can be set-up via SPI. Following
figure gives an overview about the protective functions.

4.2.1
The SPIDER - TLE7232G is protected in case of over load or short circuit of the load.
The behavior in case of over load can be configured as follows:
The over load flag (CLn) of the affected channel is cleared by a low-high transition of the
input signal. For timing information, please refer to
