TPS2055D

Texas Instruments · Power Distribution Switches · SOIC-8

TPS2055D 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 reference for the device.
2 IN power_in Input voltage to the power switch; the device operates from 2.7 V to 5.5 V and undervoltage lockout keeps the switch off when input is below approximately 2 V.
3 IN power_in Input voltage to the power switch; the device operates from 2.7 V to 5.5 V and undervoltage lockout keeps the switch off when input is below approximately 2 V.
4 EN input Enable input; logic high turns on the power switch on the TPS2055, and the input is compatible with both TTL and CMOS logic levels.
5 OC output Overcurrent logic output that is asserted active low, as an open-drain output, when an overcurrent or overtemperature condition is encountered.
6 OUT power_out Power-switch output; the switch supplies a minimum of 250 mA and the current limit is designed to 0.44 A.
7 OUT power_out Power-switch output; the switch supplies a minimum of 250 mA and the current limit is designed to 0.44 A.
8 OUT power_out Power-switch output; the switch supplies a minimum of 250 mA and the current limit is designed to 0.44 A.

Provenance

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

  • Datasheet: Texas Instruments datasheet (26 pp, sha256 ffa19a8969d40cda, retrieved 2026-10-11, 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).
