DIO7553ST6

DIOO · Power Distribution Switches · SOT-23-6

DIO7553ST6 from DIOO, 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 (2.7V to 5.5V operating range); connect a 0.1µF or greater ceramic capacitor from IN to GND as close to the IC as possible.
2 GND power_in Ground pin.
3 EN input Enable input for the DIO7553, active high: logic high turns on the power switch (VIH min 1.4V, VIL max 0.4V).
4 FAULT output Active-low open-drain output, asserted during over current, over temperature, or reverse-voltage conditions (max 6.0V, 10mA flag current).
5 ILIM passive External resistor to GND sets the current-limit threshold; recommended 10kΩ ≤ RILIM ≤ 64kΩ, IOS(A)=25752/Rset(Ω).
6 OUT power_out Power-switch output.

CAD (KiCad official)

  • Symbol: DIO7553ST6
  • Footprint: Package_TO_SOT_SMD:SOT-23-6
  • 3D model: SOT-23-6 (KiCad packages3D, STEP)
  • 3D model files: dio7553st6-etched.step / dio7553st6-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); dio7553st6.step / dio7553st6.glb are the bare package body.

Provenance

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

  • Datasheet: DIOO datasheet (11 pp, sha256 fd579156befae9d6, retrieved 2026-10-09, tier: lcsc)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-haiku-5-5 (text), consensus claude-sonnet-5-5 (agreed), guards: pin_guards 0.1: passed. Pins are checked against the footprint pad set and their cited datasheet pages before publish.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
