RH6016D from RONGHE Microelectronics, in a SOT-23-6. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | CS | passive | Sampling capacitance pin. Connect an external capacitor (typ. 10nF-47nF, Cm) between CS and GND to set the touch-detection sampling reference. |
| 2 | GND | power_in | Device ground reference (0V). |
| 3 | TCH | bidirectional | Touch channel input/output. Connects to the external touch electrode/pad, typically through a series resistor (Rs, ~5K) for ESD/noise protection. |
| 4 | TOG | input | Latch/Synchronous mode configuration input with internal pull-low resistor. TOG=0 (default, floating) selects Synchronous mode; TOG=1 (tied to VDD) selects Latch mode where OD toggles on each valid touch. |
| 5 | VDD | power_in | Supply voltage input, 2.4V to 5.5V (typ. 3.0V). Decouple with 10uF + 0.1uF to GND per application circuit. |
| 6 | OD | output | NMOS open-drain touch-detect output. High-impedance state after power-on; pulls low (IOL up to 30mA @ VOL=0.3VDD) when a valid touch is detected. Requires an external pull-up resistor to VDD for a defined logic-high level. |

## CAD (KiCad official)

- Symbol: `RH6016D`
- Footprint: `Package_TO_SOT_SMD:SOT-23-6`
- 3D model: SOT-23-6 (KiCad packages3D, STEP)
- 3D model files: `rh6016d-etched.step` / `rh6016d-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `rh6016d.step` / `rh6016d.glb` are the bare package body.
