SE809-HF-3.08V

Seaward Elec · Monitors & Reset Circuits · SOT-23

SE809-HF-3.08V from Seaward Elec, 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 reference pin for the supervisor.
2 RESET output Active-low RESET output stays low while Vcc is below the reset voltage threshold and for 150msec (typ) after Vcc rises above the threshold.
3 Vcc power_in Supply voltage input monitored against the reset threshold, with an operating input range of 2.0V to 5.5V.

CAD (KiCad official)

  • Symbol: SE809-HF-3.08V
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: se809-hf-3-08v-etched.step / se809-hf-3-08v-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); se809-hf-3-08v.step / se809-hf-3-08v.glb are the bare package body.

Provenance

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