DESCRIPTION
The AIC6165B is a cost-effective, low voltage,
single P-MOSFET load switch, optimized for
self-powered and bus-powered Universal Serial
Bus (USB) applications. This switch operates
with inputs ranging from 2.5V to 5.5V, making it
ideal for both 3V and 5V systems. The switch's
low RDS(ON), 60m, meets USB voltage drop
requirements. A built-in P-channel MOSFET
with true shutdown function to eliminate any
reversed current flow across the switch when it
is powered off. When the output voltage is
higher than input voltage, the power switch is
turned off by internal output reverse-voltage
comparator.
nFLG is an open-drain output report
over-current or over temperature event. In
addition, nFLG also has typical 2.5ms deglitch
timeout period and reports output
reverse-voltage condition.
