RH7901 from RONGHE Microelectronics, in a SOT-23-5. 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 | CB | input | Divider-mode select input: CB=0 (tied to GND) configures Divider3 (12W) for the RH7901, while CB=1 or floating configures Divider1/2. |
| 2 | GND | power_in | Negative power supply (ground) pin. |
| 3 | VDD | power_in | Positive power supply pin; the datasheet specifies VDD operation from 4.5 V to 5.5 V with absolute maximum of 5.5 V. |
| 4 | DP1 | bidirectional | CMOS input/output connected to the first USB port D+ line (DP) of the charging port. |
| 5 | DM1 | bidirectional | CMOS input/output connected to the first USB port D- line (DM) of the charging port. |
