RY2231B1D4 from RYCHIP, in a DFN-4-EP(1x1). 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 | VDD | power_in | Power supply pin; the absolute maximum VDD input voltage is -0.3 V to 6 V. |
| 2 | GND | power_in | Grounding end, connected to the battery core negative pole; the datasheet gives no separate electrical limit for this pin. |
| 3 | NC | unconnected | Not connected; the datasheet states no function for this pin. |
| 4 | VM | input | Charger minus voltage input pin; the absolute maximum VM input voltage is -6 V to 10 V. |
| 5 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
