DESCRIPTION
USB power distribution switches are high-side N-channel MOSFET switches with built-in overcurrent protection and low on-state resistance. The SC2041 switch is designed to meet the USB requirements for power switching and maintenance-free fault protection for self-powered & bus-powered hub applications.
FEATURES
• Designed to meet USB specification revisions 1.1 and 2.0 power management requirements
• 500mA continuous load current
• High-side MOSFET switch with low RDS(ON)
• Short-circuit current protection
• Internal thermal shutdown
• Undervoltage lockout
• Open drain fault output
• Soft start circuit with slow turn-on time
• Wide supply voltage range: 2.8V to 5.5V
• 2.5kV ESD rating (Human Body Model)
• Full industrial temperature range
APPLICATIONS
• Universal Serial Bus (USB) power management
• Self-powered or bus-powered USB hubs
• Root hubs in desktop PCs & servers
• Notebook PCs
• Peripherals
