**RYCHIP** · Battery Management · SOT-23-5

RY2206 from RYCHIP, 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 | GND | power_in | Ground pin for the protection IC; the datasheet gives no electrical limits for this pin beyond its function as ground. |
| 2 | GND | power_in | Ground pin for the protection IC; the datasheet gives no electrical limits for this pin beyond its function as ground. |
| 3 | VDD | power_in | Power supply pin; the absolute maximum VDD input voltage is -0.3V to 6V. |
| 4 | VM | passive | Negative terminal of the battery pack; the internal FET switch connects this terminal to GND, and the absolute maximum VM input voltage is -6V to 10V. |
| 5 | VM | passive | Negative terminal of the battery pack; the internal FET switch connects this terminal to GND, and the absolute maximum VM input voltage is -6V to 10V. |

## CAD (KiCad official)

- Symbol: `RY2206`
- Footprint: `Package_TO_SOT_SMD:SOT-23-5`
- 3D model: SOT-23-5 (KiCad packages3D, STEP)
- 3D model files: `ry2206-etched.step` / `ry2206-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `ry2206.step` / `ry2206.glb` are the bare package body.
