General Description
The MIC2027 and MIC2077 are quad high-side MOSFET switches optimized for general-purpose power distribution requiring circuit protection. The MIC2027/77 are internally current limited and have thermal shutdown that protects the device and load.

Features
• 150mΩ maximum on-resistance per channel
• 2.7V to 5.5V operating range
• 500mA minimum continuous current per channel
• Short-circuit protection with thermal shutdown
• Thermally isolated channels
• Fault status flag with 3ms filter eliminates false assertions
• Undervoltage lockout
• Reverse current flow blocking (no “body diode”)
• Circuit breaker mode (MIC2077) reduces power consumption
• Logic-compatible inputs
• Soft-start circuit
• Low quiescent current
• Pin compatible with MIC2524 and MIC2527

Applications
• USB peripherals
• General purpose power switching
• ACPI power distribution
• Notebook PCs
• PDAs
• PC card hot swap
