| | --| |-- |____| ```

  • Pin 1: VBUS (Input)
  • Pin 2: GND (Ground)
  • Pin 3: EN (Enable)
  • Pin 4: OUT (Output)
  • Pin 5: IN (Input)

Functional Features

  • Over-current protection: Automatically shuts off the power switch when the current exceeds the specified limit.
  • Thermal shutdown protection: Disables the power switch when the temperature exceeds the safe operating range.
  • Enable pin control: Allows the user to enable or disable the power switch as needed.
  • Low quiescent current: Ensures minimal power consumption when the power switch is in standby mode.
  • Fast response time: Provides quick protection against over-current events.

Advantages and Disadvantages

Advantages: - Compact size allows for easy integration into various applications. - High efficiency ensures minimal power loss during operation. - Over-current and thermal shutdown protection enhance the safety of USB ports.

Disadvantages: - Limited output voltage range may not be suitable for all applications. - Single-channel design restricts simultaneous control of multiple USB ports.

Working Principles

The FSUSB11L10X works by monitoring the current flowing through the USB port. When the current exceeds the specified limit, the over-current protection feature is triggered, and the power switch is automatically turned off to prevent damage to the connected devices. Additionally, if the temperature rises above the safe operating range, the thermal shutdown protection feature disables the power switch until the temperature returns to a safe level.
