It accepts an input voltage between 2.7V and 6.5V allowing for operations FEATURES from industry standard 3.3V and 5V power rails. Dual Channel Current Switch 1A continuous load current per channel The XRP2524 is provided with an enable pin while an error flag is available to indicate fault 1.5A Typical Over-current Limit conditions. With a low quiescent current as 2.7V to 6.5V Input Voltage Range well as a small package, the XRP2524 is ideal USB 2.0 and USB 3.0 Compliant for battery powered applications. The power- switch rise and fall times are controlled to Active High Enable minimize current surges during turn on/off. Soft Start Built-in over current, reverse current and over Channel Error Flag Indicator temperature protections insure safe operations under abnormal operating conditions. 9ms Blanking Time XRP2524 is offered in a RoHS compliant UVLO, Reverse Current, Short circuit green/halogen free 8-pin NSOIC package. and Thermal Shutdown Protection RoHS Compliant, Green/Halogen Free 8-Pin NSOIC Package TYPICAL APPLICATION DIAGRAM Fig. 1: XRP2524 Application Diagram Exar Corporation www.exar.com 48720 Kato Road, Fremont CA 94538, USA Tel. +1 510 668-7000 Fax. +1 510 668-7001 XXRRPP22552244 11AA DDuuaall CChhaannnneell UUSSBB 33..00 PPoowweerr DDiissttrriibbuuttiioonn SSwwiittcchh ABSOLUTE MAXIMUM RATINGS OPERATING RATINGS These are stress ratings only and functional operation of Input Voltage Range V ............................... 2.7V to 6.5V IN the device at these ratings or any other above those Ambient Temperature Range ..................... -40C to 85C indicated in the operation sections of the specifications Thermal Resistance .....................................160C/W JA below is not implied.
