HX809L-4.63V

HX hengjiaxing · Supervisor and Reset ICs · SOT-23

HX809L-4.63V from HX hengjiaxing, 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 Chip ground reference (芯片接地端). Connect to system ground.
3 VCC power_in Chip supply input (芯片输入端). Monitored voltage rail. Operating range 0.9 V to 6.0 V; absolute max 6 V. For the HX809L variant the reset threshold is 4.63 V ±2%.
2 RESET output Active-low reset output (复位输出端) to the host processor. VOL ≤ 0.4 V at ISINK = 3.2 mA (L/M/J variants); VOH ≥ VCC − 1.5 V at ISOURCE = 800 uA. Reset pulse Trp = 350 ms typical after VCC rises above Vth. Absolute max output current 20 mA.

Two STEP files. Same geometry, different body top:

File Size Use it when
hx809l-4-63v.step 59 KB You want the bare part, or you mark your own boards.
hx809l-4-63v-etched.step 2.0 MB You want the part with HX809L-4.63V already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 487 faces against 69 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.

Provenance

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

  • Datasheet: HX hengjiaxing datasheet (4 pp, sha256 4867890d2eebb1ee, 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).
