HG810RM3

HGSEMI · Supervisor and Reset ICs · SOT-23-3

HG810RM3 from HGSEMI, in a SOT-23-3. 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 chip. Connect to system ground.
2 RESET output Active-low reset output. Drives low when VCC falls below the detection threshold (2.63 V typ for -RM3); released high (push-pull) ~500 ms after VCC returns above threshold. VOL <= 0.3 V at ISINK = 1.2 mA; VOH >= 0.8*VCC at ISOURCE = 150 uA (for 1.8 V < VCC < Vthmin).
3 VCC power_in Supply / monitored input voltage. Operating range 1.0-6.0 V (absolute max 6.5 V). Also the voltage being sensed against the internal threshold.

CAD (KiCad official)

  • Symbol: HG810RM3
  • Footprint: Package_TO_SOT_SMD:SOT-23-3
  • 3D model: SOT-23-3 (KiCad packages3D, STEP)
  • 3D model files: hg810rm3-etched.step / hg810rm3-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); hg810rm3.step / hg810rm3.glb are the bare package body.

Provenance

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

  • Datasheet: HGSEMI datasheet (6 pp, sha256 617dd8734b6693f4, 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).
