DESCRIPTION
The AIC1521 is an integrated high-side power switch for self-powered and bus-powered Universal Serial Bus (USB) applications. The high-side switch is a MOSFET with 120mW RDS(ON), which meets USB voltage drop requirements for maximum transmission wire length. The switch ON/OFF is controlled by CTL pin.

FEATURES
• 120mΩ (5V Input) High-Side MOSFET Switch.
• 500mA Continuous Load Current.
• 80μA Typical On-State Supply Current.
• 1μA Typical Off-State Supply Current.
• Current-Limit / Short Circuit Protection.
• Thermal Limiting Protection under Overcurrent Condition.
• Undervoltage Lockout Ensures that Switch is off at Start Up.
• Output can be Forced Higher than Input (Off-State).
• Slow Turn ON and Fast Turn OFF.
• Active-High or Active-Low Enable.

APPLICATIONS
• Motherboard USB Management.
• USB Power Management.
• Hot Plug-In Power Supplies.
• Battery-Charger Circuit.
• Power Distribution Switch.
