    Quad Power Distribution Switch
    Final Information General Description Features The MIC2537 is a cost-effective high-side power switch with
    four independently controlled channels, optimized for buspowered Universal Serial Bus (USB) applications. Few external components are necessary to satisfy USB requirements.
    The MIC2537 satisfies the following USB requirements: each
    switch channel supplies up to 100mA as required by USB
    bus-powered downstream devices; fault current is limited to
    typically 250mA, 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 and 3.3V
    and 5V logic compatible enable inputs.
    The MIC2537 is available in active-high and active-low versions in a 16-lead SOP package. Compliant to USB specifications
