AIC1526
Dual USB High-Side Power Switch
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.
DESCRIPTION
The AIC1526 is a dual high-side power switch
for self-powered and bus-powered Universal
Serial Bus (USB) applications. One high-side
switch is a MOSFET with 110mΩ 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 1A,
well below the 5A safety requirement, and the
thermal shutdown function independently
controls each channel under overcurrent
condition.
Guaranteed minimum output rise time limits
inrush current during hot plug-in, minimizing
EMI and preventing the voltage at upstream port
from dropping excessively.
