SP705EN-L

MSKSEMI · Monitors & Reset Circuits · SOP-8

SP705EN-L from MSKSEMI, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 !MR input Manual reset input; a low pulse of at least 500 ns forces the reset output active.
2 VCC power_in Power supply input; SP705 operates from 5.0V to 5.5V.
3 GND power_in Ground.
4 PFI input Inverting input of the internal 1.25V power-fail comparator, with a threshold of 1.2V min, 1.25V typ and 1.3V max.
5 !PFO output Output of the internal 1.25V power-fail comparator.
6 WDI input Watchdog input with a 1.6s typical watchdog timeout; leaving the pin floating disables the watchdog function.
7 !RESET output Active-low reset signal output, asserted when VCC falls below the reset threshold or !MR is low, with a 200ms typical reset pulse width.
8 !WDO output Watchdog output, which goes low when the watchdog timer expires.

  • Symbol: SP705EN-L
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOP-8 (KiCad packages3D, STEP)
  • 3D model files: sp705en-l-etched.step / sp705en-l-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sp705en-l.step / sp705en-l.glb are the bare package body.
