APX812-46UG-7 from Diodes Incorporated, in a SOT-143. 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. |
| 2 | RESET | output | Active-high push-pull reset output on the APX812, held asserted for at least 240ms after VCC rises above the reset threshold and guaranteed valid for VCC > 1V. |
| 3 | MR | input | Active-low manual reset input; a low level forces the reset output active, with a minimum pulse width of 100 ns. |
| 4 | VCC | power_in | Operating voltage input, recommended 1.1V to 5.5V (absolute maximum -0.3 to 7V). |
