RS806-2.63YF5

Jiangsu RUNIC Tech · Supervisor And Reset ICs · SOT23-5

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.
