General Description
The AT1601 is an integrated high-side power
switch optimized for self-powered and bus-
powered Universal Serial Bus (USB) applications.
With built-in a charge pump circuitry to drive the
internal MOSFET switch, the switch’s low on-
resistance meets USB voltage drop requirements.
A flag output is available to indicate fault
conditions to the local USB controller.
The AT1601 includes soft-start to limit inrush
current during plug-in, 1.4A current limit to limit
the output current to a safe level which meet the
UL 25VA safety requirements, thermal shutdown
to prevent catastrophic switch failure from high-
current loads, under voltage lockout (UVLO) to
ensure that the device remains off unless there is a
valid input voltage present, and an enable input
that is compatible with both 3.3V and 5V logic.
