„ ^DESCRIPTION
The AIC6166 is a power switch IC integrated a
low dropout linear regulator for bus-powered
Universal Serial Bus (USB) applications.
The high-side switch of USB power switch is
MOSFET with 150m Ω R_DS(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. The output
current of USB power switch is typical limited to
0.62A / 1.25A (control by select pin).
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.
