Microchip USB333x / USB334x USB 2.0 Transceivers

Microchip USB333x / USB334x Hi-Speed USB 2.0 transceivers deliver enhanced USB functionality for the portable market with support for the latest USB-IF Battery Charging 1.1 (BC 1.1) specification. This Microchip family of USB 2.0 devices provides three times the charging current through a USB port over traditional solutions. It also dramatically reduces system bill-of-material (BOM) costs over competitive solutions. The new USB333x / USB334x provides an excellent compliment to USB charging ports by enabling portable devices to negotiate up to three times the charging current compared to a standard USB port, resulting in faster battery charging. USB333x / USB334x USB 2.0 transceivers come in small footprint packages that reduce the number of external components through the integration of voltage regulators and other discretes.

  • Highly integrated, Hi-Speed USB 2.0 transceivers:
  • Integrated VBUS over-voltage protection (up to +30V)
  • Integrated USB switch enables connector as a single port for data, charging, and audio
  • Supports wide variety of common reference clock frequencies
  • Ultra-low standby current
  • "Wrapper-less" architecture for optimized timing performance
  • Link Power Management
  • flexPWR technology provides extremely low power consumption
  • Eliminates need for external regulators
  • Eliminates need for costly external OVP IC
  • Lower BOM part count, smaller PCB footprint area
  • Longer battery life and variable I/O voltage capability
  • Digital Cameras/Video Cameras
  • Smartphones and Cell Phones
  • GPS Personal Navigation Devices
  • MP3 Players
  • External Hard Disk Drives
  • Gaming Consoles
