UIC809G-B-AE2-3-R from UTC Unisonic Tech, in a SOT-23-3. 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 reference pin for the device. |
| 2 | RESET | output | Internal active-low push-pull reset output that falls low when VCC drops below the reset threshold and stays asserted for at least 140 ms after VCC rises above the threshold. |
| 3 | VCC | power_in | Power supply input; absolute maximum rating is -0.3 V to +6.0 V, and the operating voltage range for the UIC809-B is 1 V to 6 V. |
