- DESCRIPTION
- The AIC6168 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 150mOhm 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 under voltage lockout. The output current of USB power switch is typical limited to 0.72A / 1.45A (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.
