7.4 Input and Output Leakage Current Under Overvoltage Fault

If any of the source pin voltage goes above the fault supplies (VFP or VFN), the overvoltage protection feature of the TMUX7348F-EP is triggered to turn off the switch under fault, keeping the fault channel in high-impedance state. IS(FA) and ID(FA) denotes the input and output leakage current under overvoltage fault conditions, respectively. For ID(FA) the device is disabled to measure leakage current on the drain pin without being impacted by the 40 kΩ impedance to the fault supply. When the overvoltage fault occurs, the supply (or supplies) can either be in normal operating condition (Figure 7-4) or abnormal operating condition (Figure 7-5). During abnormal operating condition, the supply (or supplies) can either be unpowered (VDD= VSS = VFN = VFP = 0 V) or floating (VDD= VSS = VFN = VFP = No Connection), and remains within the leakage performance specifications.
