General Description
The MIC2536 is a cost-effective high-side power switch, with two independently controlled channels, optimized for buspowered Universal Serial Bus (USB) applications. Few external components are necessary to satisfy USB requirements.

Features
• Compliant to USB specifications
• 2.7V to 5.5V operating range
• 150mA minimum continuous load current per channel
• 400mΩ typical on-resistance
• Fast-acting short circuit protection with
   thermal shutdown
• Integrated filter eliminates
   false overcurrent flag assertions
• Individual open-drain fault flag pins with transient filter
• 3V/5V-compatible enable inputs
• Active-high (-1) and active-low (-2) versions
• Reverse-current blocking in off mode (no “body diode”)
• Soft-start circuit
• 100µA maximum on-state supply current
• <1µA typical off-state supply current
• –40°C to 85°C operation

Applications
• USB keyboard bus-powered hubs
• USB bus-powered docking stations
• Note Book PCs
• PDAs
• General purpose power distribution applications
