TPS2553DBVR-1

Texas Instruments · AC-DC Controllers and Regulators · SOT-23-6

TPS2553DBVR-1 from Texas Instruments, in a SOT-23-6. 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.

Two STEP files. Same geometry, different body top:

File Size Use it when
tps2553dbvr-1.step 97 KB You want the bare part, or you mark your own boards.
tps2553dbvr-1-etched.step 2.5 MB You want the part with TPS2553DBVR-1 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 600 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:

  • Datasheet: Texas Instruments datasheet (38 pp, sha256 e0b8b091487f52e3, retrieved 2026-08-17, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
