HG810LM3

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

HG810LM3 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 device. Chip ground terminal.
2 RESET output Active-low reset output (push-pull). Drives low when VCC is above the 4.63 V detection threshold (Vth); pulled high when VCC falls below Vth and for a ~500 ms delay (Trp) after VCC recovers. VOL ≤ 0.3 V at ISINK = 1.2 mA; VOH ≥ 0.8·VCC at ISOURCE = 150 µA (1.8 V < VCC < Vth,min).
3 VCC power_in Supply / sense input, 1.0 V to 6.0 V (absolute max 6.5 V). Voltage monitored against the 4.63 V (±2.5%) detection threshold for the HG810LM3 variant. Typical quiescent current 2 µA at VCC = 5.5 V, no load.

  • Symbol: HG810LM3
  • Footprint: Package_TO_SOT_SMD:SOT-23-3
  • 3D model: SOT-23-3 (KiCad packages3D, STEP)
  • 3D model files: hg810lm3-etched.step / hg810lm3-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); hg810lm3.step / hg810lm3.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).
