Product data sheet
1 General description
NX20P0477 is a single-chip USB Type-C (USB-C) port overvoltage protection solution integrating a corrosion prevention algorithm from moisture. CC1/CC2 pins in the system side are protected from 28 V short to VBUS.
USB-C allows VBUS voltage to increase up to 20 V through Power delivery protocol. CC1/2 pins can be shorted to VBUS due to mechanical twisting and sliding of the connector since USB-C connector contact pins are 25 % closer to each other than a micro USB connector. Moisture or fine dust may also cause the 20 V VBUS pin to be shorted to adjacent pins.
NX20P0477 enables CC...
