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 | Input supply voltage (2.5 V to 6.5 V). Connect a 0.1 µF or greater ceramic bypass capacitor from IN to GND as close to the IC as possible. |+| 2 | GND | power_in | Ground reference for the device. For WSON package, connect externally to the PowerPAD; on SOT-23 there is no thermal pad. |+| 3 | EN | input | Enable input; logic HIGH turns on the power switch (TPS2553 is active-high; the TPS2552 variant uses active-low EN̄ on the same pin). |+| 4 | FAULT | output | Active-low open-drain fault output; asserted during overcurrent, overtemperature, or reverse-voltage conditions. Requires an external pull-up (e.g., 100 kΩ). Continuous sink current rated up to 25 mA. |+| 5 | ILIM | output | Current-limit programming pin. External resistor to GND sets current-limit threshold; recommended 15 kΩ ≤ R_ILIM ≤ 232 kΩ. ILIM source current is limited to 1 mA absolute maximum. |+| 6 | OUT | power_out | Power-switch output. Current-limited high-side switched supply to the downstream load (up to 1.5 A continuous, 1.7 A typical current-limit ceiling). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOT-23-6 |+| Category | PMIC |+| Pins | 6 |++## Ordering variants++- `TPS2553DBVRDBVR`+- `TPS2553DBVRDBVT`+- `TPS2553DBVRDRVR`+- `TPS2553DBVRDRVT`++## CAD (KiCad official)++- Symbol: `TPS2553DBVR`+- Footprint: `Package_TO_SOT_SMD:SOT-23-6`+- 3D model: SOT-23-6 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/lit/ds/symlink/tps2553.pdf) (44 pp, sha256 `8ab20570d3e126d7`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
