AIC1518
Dual USB High-Side Power Switch
FEATURES
110m(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.
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 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
1.25A, and the thermal shutdown functions of
the power switches independently control their
channel under overcurrent condition.
Guaranteed minimum output rise time limits
inrush current during hot plug-in as well as
minimizing EMI and prevents the voltage at
upstream port from dropping excessively.
