TPAX809MS3

TECH PUBLIC · Supervisor And Reset ICs · SOT-23

TPAX809MS3 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 pin.
2 RESET output Push-pull reset output that goes low when VDD falls below the reset threshold voltage and goes high only after a delay of at least 140ms once VDD rises back above the threshold.
3 VDD power_in Chip supply and monitored voltage input; absolute maximum -0.3 to +6.0 V relative to ground, operates down to 1V.

  • Symbol: TPAX809MS3
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: tpax809ms3-etched.step / tpax809ms3-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tpax809ms3.step / tpax809ms3.glb are the bare package body.
