TPS2557 - Precision Adjustable Current-Limited Power-Distribution Switches

Download the TPS2557 datasheet PDF. This datasheet also covers the TPS2556 variant, as both devices belong to the same precision adjustable current-limited power-distribution switches family and are provided as variant models within a single manufacturer datasheet.

Description

The TPS255x power-distribution switch is 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 5 A (typical) through an external resistor.

Features

  • 1 Meets USB Current-Limiting Requirements.
  • Adjustable Current Limit, 500 mA to 5 A (Typical).
  • ±6.5% Current-Limit Accuracy at 4.5 A.
  • Fast Overcurrent Response: 3.5-µs (Typical).
  • 22-mΩ High-Side MOSFET.
  • Operating Voltage: 2.5 V to 6.5 V.
  • 2-µA Maximum Standby Supply Current.
  • Built-in Soft Start.
  • 15-kV and 8-kV System-Level ESD Capable.
  • UL Listed: File No. E169910 and CB IEC60950-1- am2 ed2.0 2.
