Exar Launches USB 3.0 Ready Dual Channel Power Distribution Switch

Exar Corporation

a leading supplier of high performance analog mixed-signal components and data management solutions, today announced the XRP2524, a next-generation dual channel switch for USB V[BUS] power distribution applications.  The XRP2524 delivers 1.0A of continuous load current on each channel across USB 3.0 interconnections and enables more efficient battery charging over USB for various classes of peripherals.  The XRP2524 independently manages all aspects of the V[BUS] power distribution for two channels and provides fault protection of the host power supply and attached peripherals for events such as over current, short circuit or over temperature. Dual low on-resistance switches allow compliance with USB voltage regulation requirements while insuring control over transients during turn-on and hot plugging events. The XRP2524 seamlessly interfaces with any USB controller through channel independent active-high enable logic and fault flag.  For customers moving to USB 3.0 applications, the XRP2524 is pin compatible to Exar's SP2526.
