PRODUCTION DATA.
| PIN | I/O | DESCRIPTION | |
|---|---|---|---|
| NAME | NO. | ||
| VTX | 1 | O | Bypass pin for transmit driver supply. Connect this pin to GND via the recommended ceramic capacitor. |
| CC1 | 2 | I/O | Multifunction configuration channel interface pin to USB Type-C. Functions include connector polarity, end-device connection detect, current capabilities, and PD communication. |
| CC2 | 3 | I/O | Multifunction configuration channel interface pin to USB Type-C. Functions include connector polarity, end-device connection detect, current capabilities, and PD communication. |
| GND | 4 | — | Power ground is associated with power management and gate driver circuits. Connect to AGND and PAD. |
| HIPWR | 5 | I | Four-state input pin used to configure the voltages and currents that will be advertised. It may be connected directly to GND or DVDD, or it may be connected to GND or DVDD via a resistance R(SEL) . |
| CTL1 | 6 | O | Digital output pin used to control an external voltage regulator. |
| CTL2 | 7 | O | Digital output pin used to control an external voltage regulator. |
| EN12V / EN9V | 8 | I | For TPS25740: If it is pulled low, then the 12 V PDO may be transmitted. If it is not pulled low, the 12-V PDO will not be advertised. For TPS25740A: If it is pulled low, then the 9 V PDO may be transmitted. If it is not pulled low, the 9-V PDO will not be advertised. |
| N/C | 9 | Connect to GND. | |
| N/C | 10 | Connect to GND. | |
| UFP | 11 | O | Open drain output pin used to indicate that either CC1 or CC2 (but not both) is pulled down by a USB Type-C Sink. |
| PSEL | 12 | I | A four-state input used for selecting the maximum power that can be provided. It may be connected directly to GND or DVDD, or it may be connected to GND or DVDD via a resistance R(SEL) |
| DVDD | 13 | O | Internally regulated 1.85 V rail for external use up to 35 mA. Connect this pin to GND via the recommended bypass capacitor . |
| PCTRL | 14 | I | Input pin used to control the power that will be advertised. It may be pulled high or low dynamically. |
| GD | 15 | I | Master enable for the GDNG/GDNS gate driver. The system can drive this low to force the power path switch off. |
| VAUX | 16 | O | Internally regulated rail for use by the power management circuits. Connect this pin to GND via the recommended bypass capacitor. |
| VDD | 17 | I | Optional input supply. |
| AGND | 18 | — | Analog ground associated with monitoring and power conditioning circuits. Connect to GND and PAD. |
| ISNS | 19 | I | The ISNS input is used to monitor a VBUS-referenced sense resistor for over-current events. |
| VPWR | 20 | I | Connect to an external voltage as a source of bias power. If VDD is supplied, this supply is optional while UFP is high. |
| VBUS | 21 | I | The voltage monitor for the VBUS line. |
| GDNG | 22 | O | High-voltage open drain gate driver which may be used to drive NMOS power switches. Connect to the gate terminal. |
| GDNS | 23 | I | High-voltage open drain gate driver which may be used to drive NMOS power switches. Connect to the source terminal. |
| DSCG | 24 | O | Discharge is an open-drain output that discharges the system VBUS line through an external resistor. |
| PAD | Connect PAD to GND / AGND plane. | ||
