Single-Channel USB Power Controller Advance Information
General Description
The MIC2529 is a high-side power switch optimized for selfpowered (individual port switching) and bus-powered (ganged port switching) Universal Serial Bus (USB) hub applications.
An on-board
voltage regulator provides the 3.
3V supply
voltage needed for many USB microcontrollers reducing board component count.
The MIC2529 satisfies the following USB requirements: it 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 requirement; and a flag out...
