Overview
The NX20P0407UKZ is a single-chip USB Type-C port protection solution developed by NXP USA Inc. This integrated circuit is designed to provide robust protection for the CC1/CC2 and SBU1/SBU2 pins in USB Type-C connectors, safeguarding them against various potential hazards such as overvoltage, short circuits, and electrostatic discharge (ESD). The device is particularly important in scenarios where the USB Type-C connector's pins are susceptible to mechanical twisting, sliding, or exposure to moisture and fine dust, which can lead to short circuits with the high-voltage VBUS pin.
