TPAX803SS3

TECH PUBLIC · Supervisor and Reset ICs · SOT-23

TPAX803SS3 from TECH PUBLIC, in a SOT-23. 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 GND power_in Ground reference for the device. Connect to system ground.
2 RESET output Open-drain active-low RESET output. Remains low while VCC is below the reset threshold (2.93V typ for S version) and for at least 140ms (240ms typ) after VCC rises above the threshold. Requires an external pull-up resistor; VOL = 0.3V at ISINK=1.2mA, 0.4V at ISINK=3.2mA. Absolute max output current 20mA.
3 VCC power_in Supply voltage input. Operating range 1.0V to 5.5V; monitored against the reset threshold (2.93V typ for S version). Absolute max +6.0V; ICC = 2µA typ.

Ordering variants

  • TPAX803SS3

CAD (KiCad official)

  • Symbol: TPAX803SS3
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: tpax803ss3-etched.step / tpax803ss3-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tpax803ss3.step / tpax803ss3.glb are the bare package body.

Provenance

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

  • Datasheet: TECH PUBLIC datasheet (None pp, sha256 641ca7b8af6447af, retrieved 2026-08-17, tier: lcsc)
  • 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).
