Single High-Side Power Switch

ꢀ^FEATURES

ꢀ^DESCRIPTION

S 120mꢀ (5V Input) High-Side MOSFET Switch.

The AIC1520 is an integrated high-side power

500mA Continuous Load Current.

80ꢁA Typical On-State Supply Current.

switch for self-powered and bus-powered

Universal Serial Bus (USB) applications. The

ꢀ

Current-Limit / Short Circuit Protection.

Thermal Limiting Protection under Overcurrent

Condition.

high-side switch is a MOSFET with 120mꢀ R_DS(ON)

which meets USB voltage drop requirements for

maximum transmission wire length.

ꢀ

Undervoltage Lockout Ensures that Switch is off at

ꢀ

Start Up.

Output current is typically limited to 1.0A, well

below the 5A safety requirement, and thermal

shutdown function shuts the switch off to prevent

damage under overcurrent conditions.

Output can be Forced Higher than Input (Off-State).

ꢀ

Slow Turn ON and Fast Turn OFF.

ꢀ

Guaranteed minimum output rise time limits

inrush current during hot plug-in, minimizing EMI

and preventing the voltage at upstream port from

dropping excessively.

ꢀ^APPLICATIONS
