General Description
The MIC2526 is a dual integrated high-side power switch with
independent enable and flag functions, optimized for self-
powered and bus-powered Universal Serial Bus (USB) appli-
cations. Few external components are necessary to satisfy
USB requirements.
The MIC2526 satisfies 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 750mA, well below the UL 25VA safety require-
ments; and a flag output is available to indicate fault condi-
tions 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,
undervoltage lockout (UVLO) to ensure that the device re-
mains off unless there is a valid input voltage present, and
3.3V and 5V logic compatible enable inputs.
The MIC2526 is available in active-high and active-low ver-
sions in 8-pin DIP and SOIC packages.
