APX809S-29SA-7 from Diodes Incorporated, 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 reference pin for the supervisor. |
| 2 | RESET | output | Push-pull active-low reset output on the APX809S, asserted when VCC falls below the reset threshold and held for at least 240 ms after VCC rises above it; RESET voltage is limited to 0 to 5.5 V. |
| 3 | VCC | power_in | Operating voltage input, specified from 1.0 V to 5.5 V. |
