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.
