NX20P0407UKZ

NX20P0407UKZ is an USB Type-C CC and SBU protection IC device. It provides 28V short-to-VBUS overvoltage protection to CC1/CC2 and SBU1/SBU2 pins. USB Type-C allows VBUS voltage to increase up to 20V through Power delivery protocol. CC1/2 and SBU1/2 pins can be shorted to VBUS due to mechanical twisting and sliding of the connector since Type-C connector contact pins are 25% closer to each other than a micro USB connector. Moisture or fine dust may also cause the 20V VBUS pin to be shorted to adjacent pins. It enables CC and SBU pins to be more robust in even abnormal conditions. It is 28VDC tolerant on CON_CC1, CON_CC2, CON_SBU1 and CON_SBU2 pins in connector side and quickly disconnects switches if the voltage is above overvoltage threshold, protecting CC1, CC2, SBU1 and SBU2 in system side from high voltage. Application includes smartphone, tablet, laptop.
