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 5.5 V (abs max 7 V). Source side of the internal high-side MOSFET. Bypass with a 0.1 µF or greater ceramic capacitor from IN to GND located as close to the IC as possible. |+| 2 | GND | power_in | Device ground reference. On WSON package, connect externally to the PowerPAD. All voltages are referenced to this pin. |+| 3 | EN | input | Enable input, active high on TPS2553/TPS2553-1: logic high turns the power switch ON. Input voltage range -0.3 V to 7 V (abs max). Do not leave floating. |+| 4 | FAULT | output | Active-low open-drain fault indicator. Asserted (pulled low) during overcurrent, overtemperature, or reverse-voltage conditions. Requires an external pull-up resistor (e.g. 100 kΩ to logic rail). Continuous sink current 0-25 mA. |+| 5 | ILIM | output | Current-limit programming pin. Connect an external resistor R_ILIM from ILIM to GND to set the current-limit threshold from 75 mA to 1.7 A. Recommended 1% resistor range 15 kΩ ≤ R_ILIM ≤ 232 kΩ. ILIM source current 0-1 mA (abs max). |+| 6 | OUT | power_out | Power-switch output. Drain side of the internal high-side MOSFET. Delivers up to 1.5 A continuous to the downstream load (e.g. USB port). For USB applications bypass with ≥120 µF per hub. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOT-23-6 |+| Category | PMIC |+| Pins | 6 |++## Ordering variants++- `TPS2553DBVR-1DBVR`+- `TPS2553DBVR-1DBVT`+- `TPS2553DBVR-1DRVR`+- `TPS2553DBVR-1DRVT`++## CAD (KiCad official)++- Symbol: `TPS2553DBVR-1`+- 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/tps2553dbvr-1.pdf) (38 pp, sha256 `e0b8b091487f52e3`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
