SGM706-RYS8G

SGMICRO · Supervisor and Reset ICs · SOIC-8

SGM706-RYS8G from SGMICRO, in a SOIC-8. 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 MR input Manual Reset Input (active-low). Internal 250µA pull-up (at VCC=+5V). Can be driven by CMOS/TTL logic or a switch shorting to GND. Leave open or tie to VCC if unused.
2 VCC power_in Supply voltage pin. Operating range 1.0V to 5.5V; reset output remains valid down to VCC = 1V.
3 GND power_in Ground reference pin.
4 PFI input Power-Fail Voltage Monitor Input. Compared against internal 1.25V reference; when PFI < 1.25V, PFO goes low. Tie to GND or VCC if unused. Input current ~0.2nA.
5 PFO output Power-Fail Voltage Monitor Output (active-low, open output). Goes low when PFI < 1.25V; remains high when PFI > 1.25V. VOL ≤ 0.4V at ISINK=3.2mA.
6 WDI input Watchdog Input. Must toggle within 1.6s (TYP) timeout or WDO asserts low. Held clear during reset or when WDI is three-stated. Leave open to disable watchdog. Minimum pulse width 70ns.
7 RESET output Active-Low Reset Output. Delivers a 200ms (TYP) low pulse when VCC drops below reset threshold (2.63V for -R), MR is asserted, or watchdog expires. VOH ≥ 0.7×VCC at 800µA; VOL ≤ 0.4V at 3.2mA sink.
8 WDO output Watchdog Output (active-low). Goes low when WDI fails to toggle within the 1.6s (TYP) timeout. No minimum pulse width. Immediately high when VCC > reset threshold. VOL ≤ 0.4V at 1.2mA sink.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
sgm706-rys8g.step 122 KB You want the bare part, or you mark your own boards.
sgm706-rys8g-etched.step 2.7 MB You want the part with SGM706-RYS8G already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 649 faces against 147 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: SGMICRO datasheet (11 pp, sha256 d0c47a81727bc39d, retrieved 2026-08-17, tier: lcsc)
  • 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).
