A wide Audio-Video Equipments 1.8V to 5.5V input voltage range allows for Generic Power Switching operations from industry standard 1.8V, 3.3V and 5V power rails. FEATURES Optimized for USB V power distribution, the BUS XRP2525 and XRP2526 are compliant with the Single/Dual Channel Current Switch latest USB 3.0 specification and can be used in 900mA per channel capable any self or bus powered USB applications. The 1.15A Over-current Limit power-switch rise and fall times are controlled 1.8V to 5.5V Input Voltage Range to minimize current surges during turn on/off. USB 2.0/3.0 Compliant The XRP2525 and XRP2526 are pin and function compatible to respectively Exars Active High or Low Individual Enable SP2525A and SP2526A. Individual Channel Fault Flag Indicator Built-in over current, under voltage lockout Under voltage Lockout, Reverse (UVLO), reverse current and over temperature Current and Thermal Shutdown protections insure safe operations under Protection abnormal operating conditions. RoHS Compliant, Green/Halogen Free XRP2525 and XRP2526 are offered in a RoHS 8-Pin NSOIC Package compliant green/halogen free 8-pin NSOIC package.
