PRODUCTION DATA
The TPD3S716-Q1 provides a single-chip ESD protection and over voltage 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 TPD3S716-Q1 also provides a FLT pin that indicates to the system if a fault condition has occurred. The TPD3S716-Q1 offers ESD clamps on the VBUS_CON, VD+, and VD– pins, therefore eliminating the need for external TVS clamp circuits in the application.
The TPD3S716-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 and VD+/VD– are less than VOVP, the switches are enabled. After an internal delay the charge-pump starts-up and turns on the internal nFET switches through a soft start. At any time, if any of the external USB pins rise above their respective VOVP thresholds, the nFET switches are turned OFF and the FLT pin is pulled LOW.
