AT42QT1010-TSHR from Microchip, 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	Digital output state. Active-high push-pull output that asserts when a touch or proximity event is detected on the sense electrode.
2	VSS	power_in	Supply ground reference for the device.
3	SNSK	bidirectional	Charge-transfer sense pin connected to the external sample capacitor Cs and the sense electrode (key). Forms one terminal of the Cs sampling network.
4	SNS	bidirectional	Charge-transfer sense pin; the opposite terminal of the Cs sample capacitor from SNSK.
5	VDD	power_in	Positive supply input. Operating range 1.8 V to 5.5 V; ~17 µA typical at 1.8 V. A bypass capacitor should be tightly wired between VDD and VSS close to this pin.
6	SYNC/MODE	input	Combined SYNC input and mode-select pin. Logic level applied selects SYNC / Slow / Fast run mode (see Section 3.1).

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`at42qt1010-tshr.step`	97 KB	You want the bare part, or you mark your own boards.
`at42qt1010-tshr-etched.step`	2.3 MB	You want the part with `AT42QT1010-TSHR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 588 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.
