General Description
The MIC2529 is a high-side power switch optimized for self-powered (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.

FEATUREs
• Compliant to USB specifications
• UL Recognized Component
• On-board 3.3V, 100mA low-dropout regulator
• 500mA minimum continuous switch load current
• 160mΩ maximum on-resistance
• 750mA typical current limit
• Open-drain fault flag pin for switch
• Output can be forced higher than input (off-state)
• Thermal shutdown
• 1ms turn-on (soft-start) and fast turnoff
• Available with active-high or active-low switch enable
• Active-high enable on 3.3V regulated output
• 8-pin SOIC package

APPLICATIONs
• USB self-powered hubs
• USB bus-powered hubs
• USB keyboard hubs
