RH6015C from RONGHE Microelectronics, 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	OC	output	CMOS push-pull touch output. Active level (high/low) configured via AHLB pin. Drive strength IOL=20mA @ VOL=0.3VDD; IOH=10mA @ VOH=0.7VDD.
2	GND	power_in	Negative supply / ground reference (0V).
3	TCH	bidirectional	Touch sense input port. Connects to the capacitive sense electrode, typically through a series 1k anti-interference resistor (Rs). A sensitivity-tuning capacitor Cj (1pF-120pF, NPO/X7R recommended) is connected from this pin to GND.
4	AHLB	input	Output active-level configuration pin with internal pull-down. AHLB=0 (default): OC output is active-high on touch. AHLB=1: OC output is active-low on touch. Leave floating for default. Not effective on RH6015D open-drain variants.
5	VDD	power_in	Positive supply, 2.3V-5.5V (absolute max −0.3 to 5.5V). Typical IDD 2.5uA (low-power mode) / 5.0uA (fast mode) @ 3V. Decouple with 10uF + 0.1uF close to the pin.
6	TOG	input	Sync/Hold (toggle) mode configuration pin with internal pull-down. TOG=0 (default): sync mode-OC follows touch state. TOG=1: hold/toggle mode-OC latches on touch and retains state until next touch. Leave floating for default.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`rh6015c.step`	97 KB	You want the bare part, or you mark your own boards.
`rh6015c-etched.step`	1.6 MB	You want the part with `RH6015C` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 393 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.
