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. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | MaxLinear |+| Package | SOIC-8 |+| Category | PMIC |+| Pins | 8 |++## Ordering variants++- `SP708SEN-LSEN-L`+- `SP708SEN-LSEN-L/TR`+- `SP708SEN-LSCU-L`+- `SP708SEN-LSCU-L/TR`++## CAD (KiCad official)++- Symbol: `SP708SEN-L`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOIC-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [MaxLinear datasheet](docs/sp708sen-l-datasheet.pdf) (17 pp, sha256 `f8fc2ea49abe01d1`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
