MIC2529 Datasheet | Micrel Semiconductor

Micrel 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 ponent 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...
