TTP233H-BA6

Tontek Design Tech · Touch Sensors · SOT-23-6L

TTP233H-BA6 from Tontek Design Tech, in a SOT-23-6L. 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 Q output CMOS push-pull output. Drives IOL = 8 mA typ at VOL = 0.6 V (VDD=3V) and IOH = -4 mA typ at VOH = 2.4 V. Polarity and direct/toggle mode are set by AHLB and TOG pin-straps.
2 VSS power_in Negative power supply / system ground reference (0 V).
3 I bidirectional Input sensor port. Connects to the external touch electrode; an optional Cs capacitor (1-50 pF, NPO/X7R) to VSS tunes touch sensitivity.
4 AHLB input Active-high/low select strap for the Q output. CMOS input with internal ~25 kOhm pull-low resistor (VDD=3V). 0 (default, left open) => Q active high; 1 (tied to VDD) => Q active low.
5 VDD power_in Positive supply, 2.4 V - 5.5 V (3 V typ). A 0.1 uF (104) decoupling capacitor to VSS with short traces is required. Internal regulator drops VDD to VREG ~2.3 V for the touch sensor.
6 TOG input Output-mode select strap. CMOS input with internal ~25 kOhm pull-low resistor (VDD=3V). 0 (default, left open) => Direct output (Q follows touch); 1 (tied to VDD) => Toggle output (Q flips on each touch).

Ordering variants

Same part, different packaging or reel option.

  • TTP233H-BA6

CAD (KiCad official)

  • Symbol: TTP233H-BA6
  • Footprint: Package_TO_SOT_SMD:SOT-23-6
  • 3D model: SOT-23-6L (KiCad packages3D, STEP)
  • 3D model files: ttp233h-ba6-etched.step / ttp233h-ba6-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ttp233h-ba6.step / ttp233h-ba6.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
ttp233h-ba6.step 97 KB You want the bare part, or you mark your own boards.
ttp233h-ba6-etched.step 2.0 MB You want the part with TTP233H-BA6 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 502 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.
