8.1 Overview

The TPD3S714-Q1 provides a single-chip ESD protection and overvoltage protection solution for automotive USB interfaces. It offers short to battery protection up to 18 V and short to ground protection on VBUS_CON. The TPD3S714-Q1 also provides a FLT pin that indicates to the system if a fault condition has occurred. The TPD3S714-Q1 offers ESD clamps on the VBUS_CON, VD+, and VD– pins, thus eliminating the need for external TVS clamp circuits in the application.

The TPD3S714-Q1 has internal circuitry that controls the turnon of the internal nFET switches. An internal oscillator controls the timers that enable the switches and resets the open-drain FLT output. If VBUS_CON is less than VOVP, the switches are enabled. After an internal delay, the charge-pump starts-up, turns on the internal nFET switch through a soft start. Once the nFET is completely turned ON, TPD3S714-Q1 releases FLT pin to HIGH. At any time, if any of the external pins rise above VOVP, FLT pin is pulled LOW. The nFET switches are turned OFF.
