SP2525A SP2525A SSiinnggllee CChhaannnneell UUSSBB PPoowweerr DDiissttrriibbuuttiioonn SSwwiittcchh January 2020 Rev. 2.1.1 GENERAL DESCRIPTION APPLICATIONS The SP2525A device is an integrated high-side Self Powered USB 2.0 and 3.0 Hubs power switch ideal for self-powered and bus- USB Compliant V Power Distribution BUS powered Universal Serial Bus (USB) applications. Audio-Video Equipments Generic Power Switching The high-side switches are MOSFETs with 70m RDS(ON), which meets USB voltage drop requirements for maximum transmission wire FEATURES length. Multi-purpose open-drain fault flag output indicates over-current limiting, thermal +3.0V to +5.5V Input Voltage Range shutdown, or under voltage lockout. Output 500mA Continuous Load Current current is typically limited to 0.85A below the per Channel 5A safety requirement, and the thermal shutdown function shuts the switch off to 2.6V Undervoltage Lockout prevent damage under overcurrent conditions. 1.25A Short Circuit Current Limit Guaranteed minimum output rise time limits inrush current during hot plug-in, minimizing 100m Maximum On-Resistance EMI and preventing the voltage at the 75A On-State Supply Current upstream port from dropping excessively. 1A Shutdown Current The SP2525A is offered in a RoHS compliant green/halogen free 8-pin NSOIC package. Output can be Forced Higher than Input (Off-State) Thermal Shutdown Slow Turn On and Fast Turn Off Active-high Version: SP2525A-1 Active-low Version: SP2525A-2 RoHS Compliant, Green/Halogen Free 8-Pin NSOIC Package TYPICAL APPLICATION DIAGRAM Fig. 1: SP2525A Application Diagram Single Port Self Powered Hub 1/10 SP2525A SP2525A Single Channel USB Power Distribution Switch Single Channel USB Power Distribution Switch 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.
