TPAX809RS3

TECH PUBLIC · Supervisor and Reset ICs · SOT-23

TPAX809RS3 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 pin. Connect to system ground.
2 RESET output Active-low reset output (push-pull). Drives low when VDD falls below the reset threshold voltage (VRST = 2.63 V typ for RS3), and returns high at least 140 ms (typ 240 ms) after VDD rises back above VRST. VOL ≤ 0.3 V sinking up to 5 mA; VOH ≥ VDD−0.4 V sourcing up to 2.5 mA.
3 VDD power_in Chip supply and monitored voltage input. Operating range 1.0 V to 5.5 V; typical IVDD 8-14 µA. A bypass capacitor placed close to this pin improves supply-glitch rejection.

  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: tpax809rs3-etched.step / tpax809rs3-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tpax809rs3.step / tpax809rs3.glb are the bare package body.

Provenance

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

  • Datasheet: TECH PUBLIC datasheet (7 pp, sha256 681f7b7e04900f14, retrieved 2026-08-17, tier: lcsc)
  • Datasheet language: Chinese. Pin names, descriptions, and specs on this page were extracted and translated to English by ds2sf; the linked PDF is the manufacturer original.
  • 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).
