Overview

The TPD3S714QDBQRQ1 is a single-chip solution for short-to-battery, short-circuit, and ESDprotection for the USB connector’s VBUS and data lines in automotive USBhubs, head units, rear seat entertainment, telematics, and media interface applications. Theintegrated data switches provide best-in-class bandwidth for minimal signal degradation during USBshort-to-battery events. The high bandwidth of 1 GHz allows for a clean USB 2.0 high-speed (480Mbps) eye diagram with the long captive cables that are common in the automotive USBenvironment

The short-to-battery protection isolates the internal system circuits from anyovervoltage conditions at the VBUS_CON, VD+, and VD– pins. On these pins,the TPD3S714QDBQRQ1 can handle overvoltages up to 18 V for hot plug and DC events. The overvoltageprotection circuit provides the most reliable short-to-battery isolation in the industry, shuttingoff the switches and protecting the upstream transceiver from harmful voltage and current spikes.The VBUS_CON pin also provides an accurate current limited load switch up to0.5 A. The overcurrent protection automatically limits current to prevent drooping of the upstreamrail during short-to-ground events. Additionally, this device also integrates system level IEC61000-4-2 and ISO 10605 ESD protection on VBUS_CON, VD+, and VD– pins whichremoves the need to provide external high-voltage, low capacitance ESD diodes
