IP2726_AC_FBR_NP18W from INJOINIC, in a QFN-24-EP(4x4). 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 | VCC | power_out | Internal VCC supply output (3.1 V) that requires an external 2.2uF capacitor. |
| 2 | CMPV | input | CC loop feedback pin for optocoupler voltage regulation mode. |

| 13 | DMA | bidirectional | Connects to USB-A DM pin (20V tolerant, abs max 25 V). |
| 14 | CC2 | bidirectional | Type-C detection pin CC2 (abs max 30 V, 20V tolerant). |
| 15 | DPC | bidirectional | Connects to TYPE-C DP pin (20V tolerant, abs max 25 V). |
| 16 | DMC | bidirectional | Connects to TYPE-C DM pin (20V tolerant, abs max 25 V). |
| 17 | CC1 | bidirectional | Type-C detection pin CC1 (abs max 30 V, 20V tolerant). |
| 18 | GND | power_in | Ground. |
| 19 | NTC | input | NTC thermistor detection pin sourcing 20uA; connect 51K to GND when NTC function is unused. |
| 20 | VOUT2 | input | USB-A port discharge output supply detection pin (abs max 30 V). |
| 21 | VOUT2G | output | USB-A port output NMOS gate control pin (abs max 30 V). |
| 22 | VOUT1 | input | TYPE-C port discharge output supply detection pin (abs max 30 V). |
| 23 | VOUT1G | output | TYPE-C port output NMOS gate control pin (abs max 30 V). |
