"The AIC1528 is a dual high-side power switch for self-powered and bus-powered Universal Serial Bus (USB) applications. Both high-side switches are MOSFET with 110m Ω RDS(ON), which meets USB voltage drop requirements for maximum transmission wire length.

Multi-purpose open-drain fault flag output indicates over-current limiting, thermal shutdown, or undervoltage lockout for each channel. Output current is typically limited to 1.3A, and the thermal shutdown functions of the power switches independently control their channel under overcurrent conditions.

FEATURES

• 110mΩ (5V Input) High-Side MOSFET Switch.
• 500mA Continuous Load Current per Channel.
• 110µA Typical On-State Supply Current.
• 1µA Typical Off-State Supply Current.
• Current-Limit / Short Circuit Protection.
• Thermal Shutdown Protection under Overcurrent Condition.
• Undervoltage Lockout Ensures that Switch is off at Start Up.
• Output can be Forced Higher than Input (Off-State).
• Open-Drain Fault Flag.
• Slow Turn ON and Fast Turn OFF.
• Enable Active-High or Active-Low.

APPLICATIONS

• USB Power Management.
• Hot Plug-In Power Supplies.
• Battery-Charger Circuit.
