NXP Semiconductors

USB D+/D- Protection IC

1. General description

NX20P0408 is a single chip USB data lines protection solution. D+ and D- pins in system

side are protected from 28V short to VBUS, which pins are located near VBUS pins.

USB Type C allows VBUS voltage to increase up to 20V through Power delivery protocol,

the concern is that these D+/D- pins can be shorted with VBUS when plugging out with

mechanical twisted connector since Type C connector contact pin is 25% closer to each

other than prior generation connector, micro USB which most mobile devices have been

using. Another concern is that moisture or fine dust may cause short to 20V VBUS with

next to pins.

NX20P0408 enables D+/D- to be robust in even abnormal conditions. NX20P0408 has

28V DC tolerant on D+/D- pin in connector side and quickly disconnects switchers if the

voltage is above over voltage threshold, D+/D- in system side is protected from high

voltage.

2. Features and benefits
