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 V BUS 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
Rev. 1.1.0
