PinTeng · Touch Sensors · SOT-23-6
PT2051AT6 from PinTeng, in a SOT-23-6. 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 | QC | output | CMOS output pin whose active level (high or low) is selected by the AHLB pin, and it outputs synchronously with the touch state in LPM=0, AHLB=0 mode. |
| 2 | VSS | power_in | Ground reference pin for the device. |
| 3 | TCH | input | Touch sensing input; the trace from the touch pad to this pin should be as short as possible and must not run parallel to or cross other traces, and an optional Cs capacitor of 1 to 50 pF can be used to adjust sensitivity. |
| 4 | AHLB | input | Selects the QC output active level: 0 (default) gives active-high output and 1 gives active-low output; the pin has an internal pull-down resistor of 24 to 36 kΩ at VDD=3V. |
| 5 | VDD | power_in | Power supply pin with a working range of 2.4 to 5.5 V and an absolute maximum rating of -0 to +5.5 V, and a 104 or larger decoupling capacitor must be placed between VDD and GND as close to the pin as possible. |
| 6 | LPM | input | Low-power mode select, programmable: 0 (default) selects low-speed mode and 1 selects low-power mode; the pin has an internal pull-down resistor of 24 to 36 kΩ at VDD=3V. |
