STWD100NPWY3F

STMicroelectronics · Supervisor And Reset ICs · SOT-23-5

STWD100NPWY3F from STMicroelectronics, in a SOT-23-5. 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 WDO output Active-low watchdog output (open drain or push-pull depending on version) that is asserted when the watchdog timer expires without being cleared; an open-drain output needs an external pull-up to a supply up to 6 V (10 kΩ typical).
2 GND power_in Ground.
3 EN input Enable pin with an internal pull-down resistor (32 to 100 kΩ, 63 kΩ typ.), so the device is enabled when left floating; pulses of at least 1 µs are detected and glitches shorter than 100 ns are ignored.
4 WDI input Watchdog input that must be toggled within the watchdog timeout period tWD to clear the internal timer, otherwise WDO is asserted; pulses of at least 1 µs are detected and glitches under 100 ns are ignored.
5 VCC power_in Supply voltage, operating range 2.7 V to 5.5 V.

CAD (KiCad official)

  • Symbol: STWD100NPWY3F
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: stwd100npwy3f-etched.step / stwd100npwy3f-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); stwd100npwy3f.step / stwd100npwy3f.glb are the bare package body.
