General Description

The AP1202 series are dual integrated high-side
power switch with independent enable and flag
functions, optimized for self-powered and
bus-powered Universal Serial Bus (USB)
applications. The AP1202 series support the
following USB requirements: each switch channel
supplies up to 500mA as required by USB
downstream devices; the switch's low on-resistance
meets USB voltage drop requirements; fault current
is limited to typically 650mA, well below the UL
25VA safety requirements; and a flag output is
available to indicate fault conditions to the local
USB controller. Soft start eliminates the momentary
voltage drop on the upstream port that may occur
when the switch is enabled in bus-powered
applications.
Additional features include 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 3.3V and 5V logic compatible
enable inputs.
