USB D+/D- protection IC
Rev. 1.1 — 19 August 2019
Product data sheet
1 General description
NX20P0408 is a single chip USB data lines protection solution that provides 28V short-
to-VBUS protection to system side D+ and D- pins located near VBUS pins.
USB Type-C allows VBUS voltage to increase up to 20V through Power delivery protocol.
D+ and D- 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.
NX20P0408 enables D+/D- to be robust in even abnormal conditions. NX20P0408 is
28V DC tolerant on D+/D- pin in connector side and quickly disconnects switches if
the voltage is above overvoltage threshold, protecting D+/D- in system side from high
voltage.
