IP2721 from INJOINIC, in a TSSOP-16. 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 | VBUSG | output | Connects to the gate of the external NMOS to control the power rail, turned on when CC connection is established and off when CC disconnects. |
| 2 | VIN | power_in | Power input pin (3V to 25V working range), apply a 1uF capacitor to GND and connect to the drain of the external NMOS. |
| 3 | NC | unconnected | No connect, keep floating. |
| 4 | NC | unconnected | No connect, keep floating. |
| 5 | GND | power_in | Ground. |
| 6 | TST1 | unconnected | Reserved pin, keep floating. |
| 7 | TST2 | unconnected | Reserved pin, keep floating. |
| 8 | TST3 | unconnected | Reserved pin, keep floating. |
| 9 | NC | unconnected | No connect, keep floating. |
| 10 | NC | unconnected | No connect, keep floating. |
| 11 | SEL | input | Sets the maximum PD request voltage: High 20V, Floating 15V, GND 5V (IP2721); the level must be set before power up. |
| 12 | CC2 | bidirectional | Connects to CC2 of the USB Type-C port (PD BMC communication and connection detection). |
| 13 | CC1 | bidirectional | Connects to CC1 of the USB Type-C port (PD BMC communication and connection detection). |
| 14 | NC | unconnected | No connect, keep floating. |
| 15 | NC | unconnected | No connect, keep floating. |
| 16 | VBUS | power_in | Connects to the source of the external NMOS (load-side VBUS). |
