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. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Diodes Incorporated |+| Package | SOT-26 |+| Category | PMIC |+| Pins | 6 |++## Ordering variants++- `AP2553AW6-7W6`+- `AP2553AW6-7DC`++## CAD (KiCad official)++- Symbol: `AP2553AW6-7`+- Footprint: `Package_TO_SOT_SMD:SOT-23-6`+- 3D model: SOT-26 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Diodes Incorporated datasheet](https://www.diodes.com/assets/Datasheets/AP2553AW6-7.pdf) (17 pp, sha256 `884a4b7479034340`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
