GENERAL DESCRIPTION
The XRP2523 is a single channel integrated
high-side power distribution switch optimized
for self or bus-powered USB applications and
compliant
specification. It accepts an input voltage
between
operations from industry standard 3.3V and
5V power rails.
The XRP2523 is provided with an enable pin
with integrated soft start while an error flag is
available to indicate any fault conditions. With
a low quiescent current as well as a small
package, the XRP2523 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, under voltage lockout
(UVLO), reverse current and over temperature
protections
abnormal operating conditions.
XRP2523 is offered in a RoHS compliant
“green”/halogen free 5-pin SOT-23 package.
