NX20P0477UKZ - Single-Chip USB Type-C (USB-C) Port Overvoltage Smart Protection

Product Overviews

NX20P0477UKZ 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. NX20P0477 enables CC pins to be more robust in even abnormal conditions. NX20P0477 is 28 V DC tolerant on CON_CC pins in connector side and quickly disconnects switches if the voltage is above overvoltage threshold, protecting CC pins in system side from high voltage.
