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.
