FREMONT, Calif., Dec. 6, 2012 /PRNewswire/ -- Exar Corporation
(Nasdaq: EXAR) 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 VBUS 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
VBUS 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.
"Systems equipped with USB 3.0 compliant ports provide not only
faster data transfer speeds but also increased power to charge
peripheral and portable devices," said Eric
Pittana, Exar's Power Management
Marketing director. "With the XRP2524, designers now have
a simple and reliable solution to safely manage the extra power on
two channels at once. This device also further extends our power
distribution switch product family, which includes
the recently released XRP2523 single channel solution."
Product Details
The XRP2524 is a dual channel integrated high-side power
distribution switch optimized for self or bus-powered USB
applications. It is compliant with the latest USB 3.0 specification
and is backward compatible with the USB 2.0 specification for
a broad set of applications. The XRP2524 accepts an input
voltage between 2.7V and 6.5V allowing for operations from industry
standard 3.3V and 5V power rails. With a low quiescent current as
well as a small package, the XRP2524 is well suited for battery
powered applications. In addition, the power-switch rise and fall
times are controlled to minimize current surges during turn
on/off. The XRP2524 is provided with an enable pin as well as
a blanked error flag to indicate various fault conditions. Built-in
over current, reverse current and over temperature protections
insure safe operations under abnormal operating conditions.
Product Availability and Pricing
The XRP2524 is available now in volume quantities and comes
standard in a RoHS compliant, Halogen Free 8-Pin NSOIC
package. The 1,000-unit suggested retail is $0.75 each. Exar also offers an evaluation
board for customers to quickly and easily test the features of the
XRP2524.
