The example application utilizes the fault protection of the TMUX7308F or TMUX7309F to protect downstream components from potential miswiring conditions from the Power Module board. Figure 10-2 shows an example of positive overvoltage fault response with a fast fault ramp rate of 50 V/µs. Figure 10-3 shows the extremely flat on-resistance across source voltage while operating within a common signal range of ±10 V. These features make the TMUX7308F or TMUX7309F an ideal solution for factory automation applications that may face various fault conditions but also require excellent linearity and low distortion.
