The AIC1521 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 120m
R
DS(ON)
, which
meets USB voltage drop requirements for
maximum transmission wire length. The switch
ON/OFF is controlled by CTL pin.
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 minimum output rise time limits
inrush current during hot plug-in, minimizing EMI
and preventing the voltage at upstream port from
dropping excessively.
