STWD100YNXWY3F 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 | Watchdog output, active-low, available in open-drain or push-pull configuration; output low voltage VOL = 0.3-0.4 V at sink currents 1.2-3.2 mA. |
| 2 | GND | power_in | Ground connection. |
| 3 | EN | input | Chip enable input with 32-100 kΩ internal pull-down resistor; minimum detectable pulse width 1 µs; glitch rejection for pulses shorter than 100 ns. |
| 4 | WDI | input | Watchdog input; must toggle within timeout period tWD to prevent watchdog assertion; minimum detectable pulse width 1 µs; glitch rejection for pulses shorter than 100 ns. |
| 5 | VCC | power_in | Supply voltage with operating range 2.7-5.5 V; typical supply current consumption 13 µA. |
