PT2043AD4 from PinTeng, in a DFN-4-EP(1x1). 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 | VSS | power_in | Ground pin for the device (datasheet pin type P, ground). |
| 2 | TCH | input | Touch-sense 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 on this node sets sensitivity. |
| 3 | QC | output | CMOS output; on the PT2043AD4 it is fixed to synchronous mode with active-high output, with output source current IOH of 2 mA and sink current IOL of 15 mA at VDD=3 V. |
| 4 | VDD | power_in | Power supply input with a specified operating range of 2.4 V to 5.5 V; a capacitor of 104 or larger must be connected between VDD and GND, routed as short as possible to the VDD and VSS pins. |
| 5 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
