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.
