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.

3D model downloads

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.
