AF223

Sam wing · Touch Sensors · SOT-23-6

AF223 from Sam wing, 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 OUT output Touch key sense output. Push-pull output whose active polarity is set by AHLB and whose mode (direct/synchronous vs. toggle/hold) is set by TOG. Sink capability 20 mA at Vol=0.3VDD; source 10 mA at Voh=0.7VDD.
2 GND power_in Ground / negative supply reference (0 V).
3 KEY input Capacitive touch sensing input. Connect to the touch pad through a series 1 kΩ resistor (R1, recommended 0-5 kΩ). An optional CSEL capacitor (0-50 pF) to GND tunes sensitivity.
4 AHLB input Output polarity select. AHLB=1 (tied to VDD): OUT is active-low (idle high). AHLB=0 (tied to GND or floating): OUT is active-high (idle low). Default state 0.
5 VDD power_in Positive supply input, 2.0-5.5 V (typ 3 V). Bypass with a 100 nF capacitor to GND placed close to the pin.
6 TOG input Hold/synchronous mode select. TOG=1 (tied to VDD): OUT operates in toggle/hold (self-latching) mode. TOG=0 (tied to GND): OUT operates in synchronous/direct mode (default). In synchronous mode an internal 8 s max-active timer resets output if a key is held too long.

CAD (KiCad official)

  • Symbol: AF223
  • Footprint: Package_TO_SOT_SMD:SOT-23-6
  • 3D model: SOT-23-6 (KiCad packages3D, STEP)
  • 3D model files: af223-etched.step / af223-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); af223.step / af223.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
af223.step 97 KB You want the bare part, or you mark your own boards.
af223-etched.step 1.2 MB You want the part with AF223 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 302 faces against 117 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: Sam wing datasheet (7 pp, sha256 5e145faa59262ba6, retrieved 2026-08-17, tier: lcsc)
  • Datasheet language: Chinese. Pin names, descriptions, and specs on this page were extracted and translated to English by ds2sf; the linked PDF is the manufacturer original.
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
