SSPP22552266AA DDuuaall CChhaannnneell UUSSBB PPoowweerr DDiissttrriibbuuttiioonn SSwwiittcchh November 2011 Rev. 2.1.0 GENERAL DESCRIPTION APPLICATIONS The SP2526A device is a dual +3.0V to +5.5V Self Powered USB 2.0 and 3.0 Hubs USB Supervisory Power Control Switch ideal USB Compliant V Power Distribution BUS for self-powered and bus-powered Universal Serial Bus (USB) applications. Audio-Video Equipments Generic Power Switching Each switch has low on-resistance (110m typical) and can supply 500mA minimum. The fault currents are limited to 1.0A typical and FEATURES the flag output pin for each switch is available to indicate fault conditions to the USB +3.0V to +5.5V Input Voltage Range controller. The thermal shutdown feature will Two Independent Power Switches prevent damage to the device when subjected to excessive current loads. The undervoltage Two Error Flag Outputs, Open Drain lockout feature will ensure that the device will 2.6V Undervoltage Lockout remain off unless there is a valid input voltage present. 1.25A Short Circuit Current Limit The SP2526A is offered in a RoHS compliant 150m Maximum On-Resistance green/halogen free 8-pin NSOIC package. 110 A On-State Supply Current 1 A Shutdown Current Output can be Forced Higher than Input (Off-State) Thermal Shutdown 1ms Soft Start Power Up, Fast Turn Off Active-high Version: SP2526A-1 Active-low Version: SP2526A-2 RoHS Compliant, Green/Halogen Free 8-Pin NSOIC Package TYPICAL APPLICATION DIAGRAM Fig. 1: SP2526A Application Diagram Two Port Self Powered Hub Exar Corporation www.exar.com 48720 Kato Road, Fremont CA 94538, USA Tel. +1 510 668-7000 Fax. +1 510 668-7001 SSPP22552266AA DDuuaall CChhaannnneell UUSSBB PPoowweerr DDiissttrriibbuuttiioonn SSwwiittcchh ABSOLUTE MAXIMUM RATINGS OPERATING RATINGS These are stress ratings only and functional operation of Ambient Temperature Range ..................... -40C to 85C the device at these ratings or any other above those indicated in the operation sections of the specifications below is not implied.
