APX803-29SAG-7

Diodes Incorporated · Supervisor and Reset ICs · SOT-23

APX803-29SAG-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 reference for the supervisor. Connect to system ground.
2 RESET output Active-low, open-drain reset output. Asserted (low) whenever VCC is below the 2.93V reset threshold and held low for the reset timeout period (200ms typ) after VCC rises above the threshold. Requires an external pull-up resistor. Guaranteed valid low for VCC >= 1V; VOL <= 0.3V at ISINK = 1.2mA. Absolute max VRESET = -0.3 to 6V, IO = 20mA.
3 VCC power_in Operating voltage input; also the monitored supply. Recommended operating range 1.1V to 5.5V (absolute max 6.0V). Typical supply current 30uA. A 100nF bypass capacitor to GND is recommended (per typical applications circuit).

Two STEP files. Same geometry, different body top:

File Size Use it when
apx803-29sag-7.step 59 KB You want the bare part, or you mark your own boards.
apx803-29sag-7-etched.step 2.5 MB You want the part with APX803-29SAG-7 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 594 faces against 69 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: Diodes Incorporated datasheet (11 pp, sha256 49f1f0449cde1d5a, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
