PT2051AAD4

PinTENG(品腾) · IC · DFN-4L(1x1)

PT2051AAD4 from PinTENG(品腾), in a DFN-4L(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 TCH input Touch-sensing input for the touch pad; the trace from the pad to this pin should be as short as possible and must not run parallel to or cross other traces, with an optional Cs of 1 to 50 pF to adjust sensitivity.
2 QC output CMOS output that is active high on this package (AHLB and LPM are not bonded, and the figure note gives AHLB=0, LPM=0 as synchronous high-active output), with IOH of 2 mA min at VDD=3 V, VOH=2.1 V, and IOL of 15 mA at VDD=3 V, VOL=0.9 V.
3 VSS power_in Ground reference pin for the device.
4 VDD power_in Power supply pin with an operating range of 2.4 V to 5.5 V; a 104 (0.1 µF) or larger decoupling capacitor must be placed between VDD and GND with the shortest possible routing to the pins.
5 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
