# RY809C-293NR

**RYCHIP** · Supervisor And Reset ICs · SOT-23

RY809C-293NR from RYCHIP, in a SOT-23. 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 | GND | power_in | Ground pin of the power supply supervisor. |
| 2 | VIN | power_in | Input voltage pin; VIN absolute maximum is -0.3 V to 8.0 V, and the input voltage (VCC) operating range is 1.2 V to 7.5 V at 25°C. |
| 3 | RST | output | Reset output pin (CMOS or N-ch open drain, per the part's output option); reset threshold for this 2.93 V part is 2.89 V to 2.96 V and the reset active timeout period is 100 ms to 200 ms. |
