General Description
The MIC2073/2074 are high-side MOSFET switches optimized for general-purpose power distribution requiring circuit protection.
The MIC2073/2074 are internally current limited and have thermal shutdown for protecting the device and load.

FEATUREs
• 115 mΩ typical RBDS(ON) at 5.0 V
• 210 mΩ maximum RBDS(ON) at 5.0 V
• 2.7 V to 5.5 V operating range
• 500 mA minimum continuous current per channel
• Short circuit protection with thermal shutdown
• Thermally isolated channels
• Fault status flag (FLGA/B) separate for each channel
• 3ms fault flag delay (TD) eliminates false assertions
• UVLO (Undervoltage Lockout)
• Reverse current flow blocking (no “body diode”)
• Circuit breaker mode (MIC2074)
• Logic-compatible inputs
• Soft-start circuit
• Low quiescent current
• Pin compatible with the MIC2026/2076

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