9.3.4.6 Port Multiplexer Clamp
Each input to the 2nd stage multiplexer is clamped to prevent voltages on the port from exceeding the safe operating voltage of circuits attached to the system side of the Port Data Multiplexer. Figure 9-37 shows the simplified clamping circuit. When a path through the 2nd stage multiplexer is closed, the clamp is connected to the one of the port pins (C_USB_TP/N, C_USB_BP/N, C_SBU1/2). When a path through the 2nd stage multiplexer is not closed, then the port pin is not clamped. As the pin voltage rises above the VCLMP_IND voltage, the clamping circuit activates, and sinks current to ground, preventing the voltage from rising further.
