PRODUCTION DATA
Refer to the PDF data sheet for device specific package drawings
The TPD3S713x-Q1 is a single-chip solution for short-to-battery, short-circuit, and ESD protection for high-speed data and power lines in automotive USB hub, head unit, 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 1.2 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, DP_IN, and DM_IN pins. On these pins, the TPD3S713x-Q1 can handle overvoltages up to 18 V for hot plug and DC events and shut off the internal switches to the upstream transceiver from harmful voltage and current spikes.
The VBUS pin also provides an adjustable current limited load switch from 50 mA to 600 mA, which provides flexibility and also saves system power budget when the port requires only several tens of milliampere.
The TPD3S713x-Q1 device has a current-sense output that is able to control an upstream supply, which allows it to maintain 5 V at the remote USB port connected after a long USB cables.

PIN | TYPE(1) | DESCRIPTION | |
---|---|---|---|
NAME | NO. | ||
IMON | 1 | O | This pin sources a scaled-down ratio of current through the internal FET. A resistor from this pin to GND converts current to proportional voltage; used as an analog current monitor. |
IN | 2,3 | PWR | Input supply voltage; connect a 0.1-µF or greater ceramic capacitor from IN to GND as close to the IC as possible. |
DM_OUT | 4 | I/O | DM data line to upstream USB host controller |
DP_OUT | 5 | I/O | DP data line to upstream USB host controller |
CS | 6 | O | Linear cable compensation current. Connect to divider resistor of front-end dc-dc converter. |
EN | 7 | I | Logic-level control input for turning the power and signal switches on or off. When EN is low, the device is disabled, and the signal and power switches are OFF. |
ILIM_SEL | 8 | I | Logic-level control input for choosing the current limit resistor and current limit threshold. When ILIM_SEL = High, ILIM_HI resistor is valid; When ILIM_SEL = Low, ILIM_LO resistor is valid. |
INT1 | 9 | I | Logic-level control input, the device can be set in normal mode or client mode through pin configuration. If INT1 = high, the device is in normal mode; If INT1 = low and ILIM_SEL = Low, the device is in client mode. |
INT2 | 10 | I | For internal circuit, must connect to ground without a pull down resistor. |
GND | 11 | — | Ground connection; must be connected externally to the thermal pad. |
BIAS | 12 | PWR | Used for IEC protection. Typically, connect a 2.2-µF capacitor to ground and 5.1-kΩ resistor to BUS. |
DP_IN | 13 | I/O | DP data line to downstream connector |
DM_IN | 14 | I/O | DM data line to downstream connector |
BUS | 15,16 | PWR | Power-switch output |
NC | 17 | NC | No connect, leave floating or connect to ground. |
FAULT | 18 | O | Active-low, open-drain output, asserted during overtemperature, overcurrent, and overvoltage conditions. |
ILIM_LO | 19 | I | External resistor used to set the low current-limit threshold, selected by ILIM_SEL pin. |
ILIM_HI | 20 | I | External resistor used to set the high current-limit threshold, selected by ILIM_SEL pin. |
