TPS2045ADR

Texas Instruments · Power Distribution Switches · SOIC-8

TPS2045ADR from Texas Instruments, in a SOIC-8. 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 GND power_in Ground pin for the device.
2 IN power_in Input voltage to the power switch; the datasheet gives an operating range of 2.7 V to 5.5 V.
3 IN power_in Input voltage to the power switch; the datasheet gives an operating range of 2.7 V to 5.5 V.
4 EN input Active-low enable input; a logic low turns on the power switch and a logic high turns it off.
5 OC output Open-drain overcurrent output, active low, asserted during an overcurrent or over-temperature condition.
6 OUT power_out Power-switch output of the 80-mΩ N-channel high-side MOSFET, which current-limits at 0.5 A.
7 OUT power_out Power-switch output of the 80-mΩ N-channel high-side MOSFET, which current-limits at 0.5 A.
8 OUT power_out Power-switch output of the 80-mΩ N-channel high-side MOSFET, which current-limits at 0.5 A.

CAD (KiCad official)

  • Symbol: TPS2045ADR
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOIC-8 (KiCad packages3D, STEP)
  • 3D model files: tps2045adr-etched.step / tps2045adr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tps2045adr.step / tps2045adr.glb are the bare package body.

Provenance

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

  • Datasheet: Texas Instruments datasheet (37 pp, sha256 80a89399ce7056c2, retrieved 2026-10-08, tier: manufacturer)
  • 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).
