DESCRIPTION
The AIC1525 is an integrated high-side power
switch for self-powered and bus-powered Universal
Serial Bus (USB) applications. The high-side
switch is a MOSFET with 70mΩ R
DS(ON)
, which
meets USB voltage drop requirements for
maximum transmission wire length.

l
70mΩ (5V Input) High-Side MOSFET Switch.
500mA Continuous Load Current per Channel.
75µA 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.
Multi-purpose open-drain fault flag output
indicates over-current limiting, thermal shutdown,
or undervoltage lockout. Output current is typically
limited to 0.85A below the 5A safety requirement,
and thermal shutdown function shuts the switch
off to prevent damage under overcurrent condition.

APPLICATIONS
•
USB Power Management.
l
l
Hot Plug-In Power Supplies.
Battery-Charger Circuit.
Guaranteed minimum output rise time limits
inrush current during hot plug-in, minimizing EMI
and preventing the voltage at upstream port from
dropping excessively.
