TPS2553DBVT-1

Texas Instruments · Power Distribution Switches · SOT-23-6

TPS2553DBVT-1 from Texas Instruments, in a SOT-23-6. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 IN power_in Input voltage; connect 0.1 µF or greater ceramic capacitor from IN to GND as close to the IC as possible.
2 GND power_in Ground connection; connect externally to PowerPAD for proper heat-sinking.
3 EN input Enable input; logic high turns on power switch for TPS2553.
4 FAULT tri_state Active-low open-drain output asserted during overcurrent, overtemperature, or reverse-voltage conditions.
5 ILIM output External resistor used to set current-limit threshold; recommended 15 kΩ ≤ RILIM ≤ 232 kΩ.
6 OUT power_out Power-switch output.

CAD (KiCad official)

  • Symbol: TPS2553DBVT-1
  • Footprint: Package_TO_SOT_SMD:SOT-23-6
  • 3D model: SOT-23-6 (KiCad packages3D, STEP)
  • 3D model files: tps2553dbvt-1-etched.step / tps2553dbvt-1-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tps2553dbvt-1.step / tps2553dbvt-1.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: Texas Instruments datasheet (44 pp, sha256 88e453700cea2b26, retrieved 2026-10-03, tier: lcsc)
