USB Switches and Transceivers

Our USB switches and transceivers provide switching functions to enable a single USB port of connection in a wide range of portable and other applications like battery charging or stereo/mono microphone audio. They can also be used to implement switching between Full-Speed and Low-Speed data rates used in cell phones, digital still and video cameras, set-top boxes, IP/video phones and many other electronic devices.

USB 2.0 Switches with Battery Charging

Mobile devices, with their reduced size and minimal number of connectors, enable a single port of connectivity for transferring USB data and USB charging. Designed for use in portable devices, our Hi-Speed USB switches and port protection products offer a compelling USB solution for battery-powered mobile applications. They provide an ultra-small footprint, data multiplexing on a common connector and proven ESD protection, all at speeds of up to double the industry-required USB 2.0 bandwidth. Leveraging our RapidCharge Anywhere functionality, the USB3750 can also be used to seamlessly provide USB Battery Charging detection and detect industry-standard SE1-type chargers.

Key Features

  • Hi-Speed USB 2.0 switch with port protection
  • Single port of connectivity for transferring USB data
  • Very small footprint with minimal number of connectors
  • Primary and secondary USB charge detection for USB IF BC 1.2 and legacy devices

USB 2.0 Transceivers

Our fifth generation of highly integrated and full-featured Hi-Speed USB 2.0 transceivers based on our proven ULPI interface support a wide variety of different reference clock frequencies and also accept clocking from crystal/resonators and the ULPI 60 MHz clock-in mode. Available in traditional QFN as well as very small form-factor Wafer-Level Chip-Scale Package (WLCSP) options, this family of transceivers includes support for battery charging. They eliminate the need for external VBUS over-voltage protection ICs, USB switches, Electrostatic Discharge (ESD) protection devices and reference oscillators, minimizing your Bill of Materials and conserving valuable board space.

Key Features

  • Hi-Speed ULPI interface
  • Supports USB 2.0 OTG 2.0 specification
  • Link Power Management (LPM) capable
  • High level of integration for small-footprint and lower part count applications
  • PHYBoost technology restores USB signal integrity that has been compromised by system-level variables such as PCB layout or long cables
  • VariSense technology provides flexibility to enable late design-in compliance certification
  • Flexible clocking support for all major frequencies including ULPI Clock 60 MHz in, crystal resonator and multi frequency
