Shenzhen Fuman · Touch Sensors · SOT-23-6

TC233A from Shenzhen Fuman, 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 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).
