STMicroelectronics · Supervisor And Reset ICs · SOT-23-5
STWD100YNWWY3F 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, configurable as open drain or push-pull, asserted for tPW after the watchdog timeout tWD expires; an open-drain output needs an external pull-up to a supply up to 6 V. |
| 2 | GND | power_in | Ground reference pin for the device. |
| 3 | EN | input | Chip enable input with an internal pull-down resistor (32 kΩ to 100 kΩ), where VIH is 0.7 VCC minimum and VIL is 0.3 VCC maximum; 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, with VIH of 0.7 VCC minimum and VIL of 0.3 VCC maximum; pulses of at least 1 µs are detected and glitches shorter than 100 ns are ignored. |
| 5 | VCC | power_in | Supply voltage with an operating range of 2.7 V to 5.5 V and an absolute maximum of 7.0 V. |
