JSM8223 from JSMSEMI, 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	Touch response output. Polarity is selected by the OLH pin (OLH=0 -> active-high on touch, OLH=1 -> active-low). Behaviour vs. TCH follows either sync mode or hold/toggle mode based on the HLD pin. High-level output current spec: IOL >= 2 mA (typ 4 mA) at VOL=0.7 V.
2	GND	power_in	Ground reference for the IC. All voltages in the datasheet are referenced to GND.
3	TCH	input	Capacitive touch sense input. Connects to the external TOUCH PAD electrode. An optional tuning capacitor Cj (0-75 pF) to GND on this node reduces sensitivity; PCB trace length and pad geometry also affect sensitivity. Route away from fast-switching signals and surround with a GND guard.
4	OLH	input	Output-polarity select. Internally pulled low (default = active-high output). OLH=0: OUT drives high when touch is detected. OLH=1: OUT drives low when touch is detected. Input pull resistor RUP typ 100 kOhm (50-200 kOhm).
5	VDD	power_in	Positive supply, 2.0-5.5 V (typ 3.0 V). Bypass with >=10 uF between VDD and GND to suppress noise; supply must be stable, otherwise sensitivity drift or false detection can occur. Quiescent current ~1.5 uA typ at 3 V, SLS=1, FST=0.
6	HLD	input	Hold/Sync mode select. Internally pulled low (default = sync mode). HLD=0 (sync): OUT tracks touch presence (active only while TCH is touched). HLD=1 (hold/toggle): each touch toggles OUT and the state is latched between touches. Input pull resistor RUP typ 100 kOhm.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`jsm8223.step`	97 KB	You want the bare part, or you mark your own boards.
`jsm8223-etched.step`	1.8 MB	You want the part with `JSM8223` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 435 faces against 117 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
