223B PSSY

TDSEMIC · Touch Sensors · SOT-23-6

223B PSSY from TDSEMIC, 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 Push-pull touch-detect output. Drives up to ~10 mA sink (VOL=0.6 V) and ~6 mA source (VOH=2.4 V) at VDD=3 V. Response time up to 60 ms. Polarity and behavior (synchronous vs. level-toggle) set by STG/SLH.
2 GND power_in Ground / VSS reference.
3 SO input Touch-sense input; connects to the external touch pad. An optional series resistor Rs (100 Ω-1 kΩ) between the pad and this pin improves noise immunity. Sensitivity is tuned with a capacitor C1 (0-50 pF) from this pin to GND - larger C1 lowers sensitivity, smaller C1 raises it.
4 SLH input Output-level select (must NOT be left floating). Tie to GND for active-high output on touch (idle low); tie to VDD for active-low output on touch (idle high). Output high level tracks VDD.
5 VDD power_in Positive supply. 2.0-5.5 V operating range (typ. 3.0 V), IOP ~2.5 µA typ / 7 µA max at 3.0 V. Absolute max VSS−0.3 V to VSS+5.5 V. Decouple with 100 nF + 10 µF near the pin (per application circuit).
6 STG input Mode-select strap (must NOT be left floating). Tie to GND for synchronous output mode (output follows touch duration, max touch time 6 s). Tie to VDD for level-toggle (self-locking) mode (output toggles on each touch, max touch time 6 s).

  • Symbol: 223B PSSY
  • Footprint: Package_TO_SOT_SMD:SOT-23-6
  • 3D model: SOT-23-6 (KiCad packages3D, STEP)
  • 3D model files: 223b-pssy-etched.step / 223b-pssy-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); 223b-pssy.step / 223b-pssy.glb are the bare package body.

Provenance
