PinTeng · Touch Sensors · SOT-23-6

PT2021WT06 from PinTeng, 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 TCH input Single-channel capacitive touch sensor input; external sampling capacitor typically 10-47 nF depending on material type.
2 VSS power_in Power supply negative (ground), reference voltage for all signal pins.
3 CMOD output Sampling capacitor input pin; connect capacitor (10-47 nF) between this pin and ground to adjust touch sensitivity, larger values increase sensitivity.
4 OPT input Mode setting pin; input state at power-up determines LED brightness sequence: connect to VDD or leave floating for 100%-40%-10%-off, or connect to VSS for 10%-40%-100%-off.
5 VDD power_in Power supply positive, operating voltage range 2.4 to 5.5 V.
6 OUT output LED output pin with three brightness levels (100%, 40%, 10%) and off state; source current up to 4.5 mA (VOH=9/10VDD) and sink current up to 28 mA (VOL=1/3VDD).
