Functional Features

  • Seamless switching between two USB sources
  • Low insertion loss for minimal signal degradation
  • High bandwidth for fast data transfer
  • Support for both data and charging modes
  • Low power consumption for energy efficiency

Advantages and Disadvantages

Advantages: - High-speed USB 2.0 switching capability - Compact package size for space-constrained applications - Low power consumption for energy-efficient operation - Support for data and charging modes enhances versatility

Disadvantages: - Limited to USB 2.0 specifications, not compatible with USB 3.0 or higher

Working Principles

The PI3USB32XAEX operates by selectively connecting either of the two USB sources to the output based on the control signal provided at the SEL pin. When SEL is set to logic low, IN1 is connected to the output, and when SEL is set to logic high, IN2 is connected to the output. This allows seamless switching between the two USB sources.

Detailed Application Field Plans

The PI3USB32XAEX finds applications in various fields, including:

  1. Mobile devices: Enables switching between different USB sources such as data cables and charging adapters.
  2. Computing: Facilitates multiplexing between USB peripherals and host devices.
  3. Consumer electronics: Allows for flexible connectivity options between USB devices.
