# APX809S00-46SA-7

**Diodes Incorporated** · Supervisor and Reset ICs · SOT-23

APX809S00-46SA-7 from Diodes Incorporated, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | GND | power_in | Ground return for the device. Connect to system ground. |
| 2 | RESET | output | Active-low push-pull reset output (RESET-bar). Asserts low when VCC falls below the preset threshold (VTH = 4.63V typ for the -46 option) and remains low for the reset active timeout period (1.7ms typ for the S00 option) after VCC rises above VTH. Guaranteed valid down to VCC = 1V. Output drives up to ~500µA sourcing and up to 3.2mA sinking. |
| 3 | VCC | power_in | Operating voltage / monitored supply input. Recommended operating range 1.0V to 5.5V; absolute max 6.0V. Also serves as the sensed supply for the internal reset comparator. |

## CAD (KiCad official)

- Symbol: `APX809S00-46SA-7`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23 (KiCad packages3D, STEP)
- 3D model files: `apx809s00-46sa-7-etched.step` / `apx809s00-46sa-7-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `apx809s00-46sa-7.step` / `apx809s00-46sa-7.glb` are the bare package body.
