Exar announces next-generation single channel switch for USB
Michael McManus, DIGITIMES, Taipei [Friday 26 October 2012]

Exar, a provider of high performance analog mixed-signal and data management products, has announced the XRP2523, a next-generation single channel switch for USB VBUS power distribution applications. The XRP2523 is compliant with the latest USB 3.0 specification as well as the established USB 2.0 specification. The new specification provides higher power to the downstream peripherals and enables more efficient battery charging over USB.

The XRP2523 manages all aspects of the VBUS power distribution; providing a low on-resistance to meet the USB voltage regulation requirement, controlling transients during turn-on and hot plugging events and handling all fault conditions such as over current, short circuit or over temperature. The XRP2523 seamlessly interfaces with any USB controller through an active-high enable logic and channel fault flag.

The XRP2523 is available in volume quantities and comes standard in a RoHS compliant, halogen free 5-pin SOT-23 package. The 1,000-unit suggested retail is US$0.69 each. Exar also offers an evaluation board for customers to quickly and easily test the features of the XRP2523.
