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
