GENERAL DESCRIPTION
The XRP2527 and XRP2528 devices are
respectively single and dual channel integrated
high-side power distribution switches with
independent enables, fault flags and precise
programmable current limit thresholds. A wide
1.8V to 5.5V input voltage range allows for
operations from industry standard 1.8V, 3.3V
and 5V power rails.
Current limit thresholds can be programmed
accurately and independently for each channel
via an external resistor. A simple setting
optimizes the XRP2527 and XRP2528 for use
in USB 2.0 or 3.0 compliant V BUS power
distribution architectures. These devices 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.
Built-in over current, under voltage lockout
(UVLO), reverse current and over temperature
protections insure safe operations under
abnormal operating conditions.
XRP2527 and XRP2528 are offered
respectively in RoHS compliant
“green”/halogen free 3mm x 3mm 8-pin and
10-pin TDFN packages.
