The example application utilizes adjustable fault threshold voltages of the TMUX7462F to allow for protection of downstream components operating on lower supply voltages. Figure 9-2 shows an example of positive overvoltage fault response with a fast fault ramp rate of 60 V/us. Figure 9-3 shows the extremely flat on-resistance across source voltage while operating within the fault threshold voltage levels for many supply voltage scenarios. These features make the TMUX7462F an excellent solution for data acquisition applications that may face various fault conditions but also require excellent linearity and low distortion.
