XRP2524
1A Dual Channel USB 3.0 Power Distribution Switch
October 2012
GENERAL DESCRIPTION
The XRP2524 is a dual channel integrated
high-side power distribution switch optimized
for self or bus-powered USB applications and it
is compliant with the latest USB 3.0
specification. It accepts an input voltage
between 2.7V and 6.5V allowing for operations
from industry standard 3.3V and 5V power
rails.
The XRP2524 is provided with an enable pin
while an error flag is available to indicate fault
conditions. With a low quiescent current as
well as a small package, the XRP2524 is ideal
for battery powered applications. The power-
switch rise and fall times are controlled to
minimize current surges during turn on/off.
Built-in over current, reverse current and over
temperature protections insure safe operations
under abnormal operating conditions.
XRP2524 is offered in a RoHS compliant
“green”/halogen free 8-pin NSOIC package.
