Overview

BL2556 is an adjustable current-limiting threshold USB interface output protection IC designed for 5V applications. It integrates overcurrent protection, short-circuit protection, over-temperature protection, and undervoltage protection. When the output experiences overcurrent, short-circuit, or startup with large capacitive loads, it limits the current output to protect the upstream power supply.

Applications

  • USB bus/self-powered hubs
  • USB peripherals
  • Notebook computers
  • Tablet battery chargers

Key features

  • 70mΩ on-resistance
  • Adjustable current limit threshold via external resistor
  • Current limit threshold tolerance over full operating range: ±15%
  • Fast response protection against output short circuit, suppressing inrush current
  • No substrate diode, prevents reverse current flow when chip is disabled
