General Description
The AP1212 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.
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 1000mA, 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.
