AP2553AW6-7

Diodes Incorporated · AC-DC Controllers and Regulators · SOT-26

AP2553AW6-7 from Diodes Incorporated, in a SOT-26. 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 IN power_in Power input, 2.7 V to 5.5 V. Connect a 0.1 µF or larger ceramic bypass capacitor from IN to GND as close to the IC as possible.
2 GND power_in Ground return for the device.
3 EN input Active-high enable input. Logic high turns the power switch on; logic low disables the switch and activates the internal output discharge path (~600 Ω). VIH ≥ 2.0 V, VIL ≤ 0.8 V.
4 FAULT output Active-low open-drain fault output. Asserted during over-current, over-temperature, or reverse-voltage conditions after an 8 ms internal deglitch. Requires an external pull-up resistor (e.g. 10 kΩ) to the logic rail; sink current ≤ 10 mA.
5 ILIM passive Current-limit programming pin. Connect an external resistor RLIM from ILIM to GND to set the current-limit threshold; recommended 10 kΩ ≤ RLIM ≤ 210 kΩ, giving ILIMIT from ~2.36 A down to ~75 mA (typ). ILIM source current ≤ 1 mA.
6 OUT power_out Switched power output to the load. Internal PMOS pass FET (RDS(on) ≈ 70 mΩ typ at VIN = 5 V) connects IN to OUT when enabled. USB applications require ≥120 µF of output capacitance.

CAD (KiCad official)

  • Symbol: AP2553AW6-7
  • Footprint: Package_TO_SOT_SMD:SOT-23-6
  • 3D model: SOT-26 (KiCad packages3D, STEP)
  • 3D model files: ap2553aw6-7-etched.step / ap2553aw6-7-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ap2553aw6-7.step / ap2553aw6-7.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
ap2553aw6-7.step 97 KB You want the bare part, or you mark your own boards.
ap2553aw6-7-etched.step 2.0 MB You want the part with AP2553AW6-7 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 499 faces against 117 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:
