TPS2555 - Power-Distribution Switches

Download the TPS2555 datasheet PDF. This datasheet also covers the TPS2554 variant, as both devices belong to the same power-distribution switches family and are provided as variant models within a single manufacturer datasheet.

General Description

The TPS2554/55 power-distribution switches are intended for applications where precision current limiting is required or heavy capacitive loads and short circuits are encountered.

These devices offer a programmable current-limit threshold between 500 mA and 2.5 A (typ) via an external resistor.

Key Features

  • 1.
  • 2 Meets USB Current-Limiting Requirements.
  • Adjustable Current Limit, 500 mA to 2.5 A (typ).
  • Two Independently-Settable, Current-Limit Thresholds.
  • Fast Overcurrent Response - 1.5 μs (typ).
  • 73-mΩ High-Side MOSFET.
  • 3.8-μA Maximum Standby Supply Current.
  • PowerPAD™ Thermal Management.
  • Automatic Output Discharge when Disabled.
  • Both High-Enable (TPS2554) and Low-Enable (TPS2555) Versions Available.
