PT8022W-S08
PinTeng · Touch Sensors · SOP-8
PT8022W-S08 from PinTeng, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | NC | unconnected | No connection; the datasheet assigns no function to this pin (Table 1 lists it as NC). |
| 2 | CMOD | bidirectional | Sampling capacitor input: a capacitor Cm between CMOD and GND sets touch sensitivity, with larger values giving higher sensitivity (e.g., 10nF for 3mm acrylic). |
| 3 | VDD | power_in | Positive supply input with an operating range of 2.4 V to 5.5 V and an absolute maximum rating of 6.0 V. |
| 4 | VSS | power_in | Negative supply / ground reference pin for the device. |
| 5 | TCH | bidirectional | Touch input pin for the single capacitive touch channel, controlling the SO PWM output. |
| 6 | OPT1 | bidirectional | Option input 1 with internal pull-up, sampled at power-up together with OPT2 to select one of four function modes (floating = 1, tied to GND = 0). |
| 7 | SO | bidirectional | PWM LED dimming output at 20 kHz, with the source and sink current limits given in the DC characteristics (e.g., 12 mA sink at VDD=5V, VOL=1/10VDD). |
| 8 | OPT2 | bidirectional | Option input 2 with internal pull-up, sampled at power-up together with OPT1 to select one of four function modes (floating = 1, tied to GND = 0). |
