TPD3S713QRVCRQ1 from Texas Instruments, in a WQFN-20(3x4). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | IMON | output | Sources a scaled-down ratio of the current through the internal FET; a resistor from this pin to GND converts it to a proportional voltage for analog current monitoring. |
| 2 | IN | power_in | Input supply voltage with a recommended operating range of 4.5 V to 5.5 V; connect a 0.1-µF or greater ceramic capacitor from IN to GND as close to the IC as possible. |
| 3 | IN | power_in | Input supply voltage with a recommended operating range of 4.5 V to 5.5 V; connect a 0.1-µF or greater ceramic capacitor from IN to GND as close to the IC as possible. |
| 4 | DM_OUT | bidirectional | DM data line to the upstream USB host controller; recommended voltage range 0 to 3.6 V. |
| 5 | DP_OUT | bidirectional | DP data line to the upstream USB host controller; recommended voltage range 0 to 3.6 V. |
| 6 | CS | output | Linear cable compensation current output; connect to the divider resistor of the front-end dc-dc converter. |
| 7 | EN | input | Logic-level control input that turns the power and signal switches on or off; when EN is low the device is disabled and both switches are off. |
| 8 | ILIM_SEL | input | Logic-level control input selecting the current-limit resistor and threshold: high selects ILIM_HI, low selects ILIM_LO. |
| 9 | INT1 | input | Logic-level control input selecting normal mode (INT1 high) or client mode (INT1 low with ILIM_SEL low). |
| 10 | INT2 | input | For internal circuit use; must be connected to ground without a pull-down resistor. |
| 11 | GND | power_in | Ground connection; must be connected externally to the thermal pad. |
| 12 | BIAS | power_in | Used for IEC protection; typically connect a 2.2-µF capacitor to ground and a 5.1-kΩ resistor to BUS; absolute maximum voltage is 18 V. |
| 13 | DP_IN | bidirectional | DP data line to the downstream connector; absolute maximum voltage is 18 V. |
| 14 | DM_IN | bidirectional | DM data line to the downstream connector; absolute maximum voltage is 18 V. |
| 15 | BUS | power_out | Power-switch output (VBUS); absolute maximum voltage is 18 V. |
| 16 | BUS | power_out | Power-switch output (VBUS); absolute maximum voltage is 18 V. |
| 17 | NC | unconnected | No connect; leave floating or connect to ground. |
| 18 | FAULT | output | Active-low, open-drain output asserted during overtemperature, overcurrent, and overvoltage conditions; recommended continuous sink current is 10 mA maximum. |
| 19 | ILIM_LO | input | External resistor sets the low current-limit threshold, selected by ILIM_SEL; current-limit-set resistors range from 6.98 kΩ to 100 kΩ. |
| 20 | ILIM_HI | input | External resistor sets the high current-limit threshold, selected by ILIM_SEL; current-limit-set resistors range from 6.98 kΩ to 100 kΩ. |
| 21 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
