DESCRIPTION
The AIC1518 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.
FEATURES
• 110mΩ (5V Input) High-Side MOSFET Switch.
• 1A Continuous Load Current per Channel.
• 110µA Typical On-State Supply Current.
• 1µA Typical Off-State Supply Current.
• Current-Limit / Short Circuit Protection.
• Fault Flag with 3ms filter eliminates false
assertions. (1518D)
• Thermal Shutdown Protection under Overcurrent
Condition.
• Undervoltage Lockout Ensures that Switch is off
at Start Up.
• 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.
