AM01B from Sam wing, in a SOT-23-6L. 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 key sense output. Push-pull digital output driving up to 20 mA sink current (Vol = 0.3 x VDD). Polarity (active-high/low) is set by VGM; mode (hold/sync/toggle) is set by HMD.
2	GND	power_in	Ground / negative supply reference. 0 V rail.
3	KEY	input	Capacitive touch sense input. Connects to the sense pad through a series resistor R1 (~1 kOhm typical, 0-5 kOhm recommended). An optional CSEL capacitor to GND (0-50 pF) adjusts sensitivity; minimum detectable delta capacitance is 0.2 pF.
4	VGM	input	Output-polarity select. Tie high: OUT is active-low (idle high, low when touched). Tie low or leave floating: OUT is active-high (idle low, high when touched). Default state = 0 (active-high).
5	VDD	power_in	Positive supply input, 2.3 V to 5.5 V (3 V typical). Recommend a 100 nF (104) decoupling capacitor placed as close to VDD as possible. Absolute max -0.3 V to +5.5 V.
6	HMD	input	Output-mode select. Tie high: OUT is in hold (toggle/self-lock) mode - each touch flips the output. Tie low: OUT is in sync (direct) mode - output follows the touch. Default state = 0 (sync mode).

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`am01b.step`	97 KB	You want the bare part, or you mark your own boards.
`am01b-etched.step`	1.1 MB	You want the part with `AM01B` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 292 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.
