XRP2525 - XRP2526
Single/Dual Channel USB 3.0 Power Distribution Switch
Rev. 1.1.0
GENERAL DESCRIPTION
The XRP2525 and XRP2526 devices are
respectively single and dual channel integrated
high-side power distribution switches with
independent enables and fault flags. A wide
1.8V to 5.5V input voltage range allows for
operations from industry standard 1.8V, 3.3V
and 5V power rails.
Optimized for USB VBUS power distribution, the
XRP2525 and XRP2526 are compliant with the
latest USB 3.0 specification and can be used in
any self or bus powered USB applications. The
power-switch rise and fall times are controlled
to minimize current surges during turn on/off.
The XRP2525 and XRP2526 are pin and
function compatible to respectively Exar’s
SP2525A and SP2526A.
Built-in over current, under voltage lockout
(UVLO), reverse current and over temperature
protections insure safe operations under
abnormal operating conditions.
XRP2525 and XRP2526 are offered in a RoHS
compliant “green”/halogen free 8-pin NSOIC
package.
