AIC1528
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.
DESCRIPTION
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 R_DS(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 condition.
APPLICATIONS
USB Power Management.
Hot Plug-In Power Supplies.
Battery-Charger Circuit.
