DUAL USB HIGH-SIDE POWER SWITCH
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. The AP1212 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 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.
