RS806-2.63YF5 from Jiangsu RUNIC Tech, in a SOT23-5. 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 | RESET | output | Active-low reset output pulses low for 200ms when triggered and stays low whenever VCC is below the reset threshold. |
| 2 | GND | power_in | Ground, the reference for all signals. |
| 3 | MR | input | Active-low manual-reset input triggers a reset pulse when pulled below 0.1*VCC, has an internal pull-up resistance, and can be shorted to ground with a switch. |
| 4 | WDI | input | Watchdog input: if WDI remains high or low for 1.6 s the watchdog timer expires and RESET goes low, while floating WDI or a high-impedance three-state driver disables the watchdog. |
| 5 | VCC | power_in | Power supply voltage that is monitored by the supervisor. |
