Description
AI
The TPD3S714-Q1 is a single-chip solution for short-to-battery, short-circuit, and ESD protection for the USB connector’s VBUSand 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 overvoltage conditions at the VBUS_CON, VD+, and VD– pins. On these pins, the TPD3S714-Q1 can handle overvoltages up to 18 V for hot plug and DC events. The overvoltage 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_CONpin also provides an accurate current limited load switch up to 0.5 A. The overcurrent 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
