TPAX803RS3

TECH PUBLIC · Supervisor And Reset ICs · SOT-23

TPAX803RS3 from TECH PUBLIC, in a SOT-23. 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 GND power_in Ground.
2 RESET output Open-drain active-low reset output that stays low while VCC is below the reset threshold and for at least 140ms after VCC rises above it.
3 VCC power_in Supply voltage input for +5V, +3.3V, +3V or +2.5V supplies, with a 1.0V to 5.5V operating range (absolute maximum -0.3V to +6.0V).

  • Symbol: TPAX803RS3
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: tpax803rs3-etched.step / tpax803rs3-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tpax803rs3.step / tpax803rs3.glb are the bare package body.
