sp708sen-l.lbr rebuild the library on adom-lbr 2.32.0. The published copy was built by 2.18.0, which imported every KiCad roundrect and oval pad as a SQUARE EAGLE smd; this carries the real pad shape across (0 -> 8 rounded pads) and stops dropping geometry drawn on KiCad User.N layers. Attributes, connects, pads and the pin-1 marker are gated against decreasing and are unchanged. · Ray 1mo ago

SP708SEN-L

MaxLinear · Supervisor and Reset ICs · SOIC-8

SP708SEN-L from MaxLinear, 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 (active LOW, overbarred). Triggers a reset pulse when pulled below 0.8V. Has an internal ~70µA pull-up to VCC; can be driven by a TTL/CMOS line or a switch to GND.
2 VCC power_in Supply voltage input. Operating range 1.0V-5.5V; typical 3.15V-5.5V for the SP708S variant. Typical supply current 25µA @ 3.3V.
3 GND power_in Ground reference for all signals.
4 PFI input Power-Fail comparator Input. When PFI < 1.25V (internal reference), PFO is driven LOW. Tie to GND or VCC when unused. Input current ±200 nA max.
5 PFO output Power-Fail comparator Output. Driven LOW while PFI < 1.25V, HIGH otherwise. Push-pull CMOS output (VOH ≥ 0.8×VCC at 500µA source; VOL ≤ 0.3V at 1.2mA sink).
6 NC unconnected No internal connection on SP708R/S/T. Leave floating or tie to GND.
7 /RESET output Active-LOW reset output (overbarred RESET). Pulses LOW for 200ms whenever VCC dips below the 2.93V reset threshold or when MR is asserted, and holds LOW for 200ms after VCC recovers.
8 RESET output Active-HIGH reset output. Complement of /RESET (pin 7): HIGH while a reset is asserted, LOW otherwise. VOH ≥ VCC-0.6V at 215µA source; VOL ≤ 0.3V at 1.2mA sink.

CAD (KiCad official)

  • Symbol: SP708SEN-L
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOIC-8 (KiCad packages3D, STEP)
  • 3D model files: sp708sen-l-etched.step / sp708sen-l-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sp708sen-l.step / sp708sen-l.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
sp708sen-l.step 122 KB You want the bare part, or you mark your own boards.
sp708sen-l-etched.step 2.0 MB You want the part with SP708SEN-L already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 502 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: MaxLinear datasheet (17 pp, sha256 f8fc2ea49abe01d1, retrieved 2026-08-17, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
