Single High-Side Power Switch

DESCRIPTION

The AIC1520 is an integrated high-side power

switch

Universal Serial Bus (USB) applications. The

high-side switch is a MOSFET with 120mW R

which meets USB voltage drop requirements for

maximum transmission wire length.

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.

Guaranteed

inrush current during hot plug-in, minimizing EMI

and preventing the voltage at upstream port from

dropping excessively.
