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 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 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.

Note 1: Specifications are production tested at TA=25°C. Specifications over the -40°C to 85°C operating
temperature range are assured by design, characterization and correlation with Statistical Quality
Controls (SQC).
The AIC6166 requires minimum CUSBIN = 0.8μF and CUSBOUT = 1μF to maintain stability. For best
performance, typically use CUSBIN = 1μF, CUSBOUT = 2.2μF (ceramic) + 22μF (aluminum).
Note 2: When thermal shutdown, the IC performs the function of latching in OFF state. It can resume operation
by turning off once (min. 1uS) and then turn on using the CTL pin (with Typ. 25℃ Thermal Shutdown
Hysteresis), or by restoring power to the USBIN pin.
