TPD3S714QDBQRQ1 Datasheet PDF - TI

The TPD3S714-Q1 is a single-chip solution for short-to-battery, short-circuit, and ESD protection for the USB connector’s VBUS and data lines in automotive USB hubs, head units, rear seat entertainment, telematics, and media interface applications. The integrated data switches provide best-in-class bandwidth for minimal signal degradation during USB short-to-battery events. The high bandwidth of 1-GHz allows for a clean USB 2.0 high-speed (480-Mbps) eye diagram with the long captive cables that are common in the automotive USB environment

●The short-to-battery protection isolates the internal system circuits from any over-voltage conditions at the VBUS_CON, VD+, and VD– pins. On these pins, the TPD3S714-Q1 can handle over-voltages up to 18 V for hot plug and DC events. The over-voltage protection circuit provides the most reliable short-to-battery isolation in the industry, shutting off 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 to 0.5 A. The over-current protection automatically limits current to prevent drooping of the upstream rail during short-to-ground events. Additionally, this device also integrates system level IEC 61000-4-2 and ISO 10605 ESD protection on VBUS_CON, VD+, and VD– pins which removes the need to provide external high-voltage, low capacitance ESD diodes
