Diagnosis

Due to the fact that Output Status Monitor checks the voltage level at the outputs in real time, for Open Load

in OFF diagnostic it is necessary to synchronize the reading of DIAG_OSM register with the OFF state of the

channels.

Figure 25, Figure 26 and Figure 27 shows how Output Status Monitor is implemented at concept level.

Figure 25 Output Status Monitor - concept (auto-configurable channel as High-Side)
