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 | OUT | output | Trigger drive output. Open-drain, active-low; requires external pull-up (typ. 10 kΩ) if internal pull-up is not used. Sink current typ. 26 mA at VDD=4V. |+| 2 | GND | power_in | Ground / power negative terminal. |+| 3 | TCH | input | Touch sensing input pin. Connects to the touch pad through a series resistor (R2, 0-5 kΩ, typ. 1 kΩ) with an optional sensitivity-trim cap (C2, 0-47 pF) to GND. |+| 4 | LHO | input | Output polarity select. Tie to VDD for active-low OUT operation (as described by the datasheet). |+| 5 | VDD | power_in | Positive supply. Operating range 2.3V-5.5V (typ. 3V). Decouple with 100 nF (C1) close to the pin. |+| 6 | OHO | input | Output mode select (One-shot or Hold). Tie to VDD for Hold mode (OUT stays asserted while touched); tie to GND for synchronous / one-shot mode (OUT tracks touch with a 16 s max active-time watchdog). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Shenzhen Fuman |+| Package | SOT-23-6 |+| Category | Sensor |+| Pins | 6 |++## CAD (KiCad official)++- Symbol: `TC233A`+- Footprint: `Package_TO_SOT_SMD:SOT-23-6`+- 3D model: SOT-23-6 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Shenzhen Fuman datasheet](docs/tc233a-datasheet.pdf) (4 pp, sha256 `aa22b7ed6928a34d`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
