RH6016D 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	CS	passive	Sampling capacitance pin. Connect an external capacitor (typ. 10nF-47nF, Cm) between CS and GND to set the touch-detection sampling reference.
2	GND	power_in	Device ground reference (0V).
3	TCH	bidirectional	Touch channel input/output. Connects to the external touch electrode/pad, typically through a series resistor (Rs, ~5K) for ESD/noise protection.
4	TOG	input	Latch/Synchronous mode configuration input with internal pull-low resistor. TOG=0 (default, floating) selects Synchronous mode; TOG=1 (tied to VDD) selects Latch mode where OD toggles on each valid touch.
5	VDD	power_in	Supply voltage input, 2.4V to 5.5V (typ. 3.0V). Decouple with 10uF + 0.1uF to GND per application circuit.
6	OD	output	NMOS open-drain touch-detect output. High-impedance state after power-on; pulls low (IOL up to 30mA @ VOL=0.3VDD) when a valid touch is detected. Requires an external pull-up resistor to VDD for a defined logic-high level.
