ZHCSH46A December 2017 – June 2018 AMC1311
The AMC1311 offers a fail-safe output that simplifies diagnostics on system level. The fail-safe output is active in three cases:
Figure 48 shows the fail-safe output of the AMC1311 that is a negative differential output voltage that does not occur under normal device operation. As a reference value for the fail-safe detection on a system level, use the VFAILSAFE voltage as specified in the Electrical Characteristics table.
