AIC1529

Quad USB High-Side Power Switch

FEATURES

• 110mΩ (5V Input) High-Side MOSFET Switch.

500mA Continuous Load Current per Channel.

220µA 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 AIC1529 is a quad high-side power switch

for self-powered and bus-powered Universal

Serial Bus (USB) applications. Both high-side

switches are 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 1.3A, 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.
