General Description
The MIC2505, MIC2505-1, MIC2505-2, and MIC2506 are single and dual integrated high-side power switches that consist of TTL compatible control/enable inputs, a charge pump, and protected N-channel MOSFETs. The MIC2505/6 family can be used instead of separate high-side drivers and MOSFETs in many low-voltage applications.

Features
• Low MOSFET on resistance to 2.7V
   30mΩ typical at 5V (MIC2505-series)
   35mΩ typical at 3.3V (MIC2505-series)
   75mΩ typical at 5V (each MIC2506 output)
   80mΩ typical at 3.3V (each MIC2506 output)
• 2.7V to 7.5V input
• 110µA typical on-state supply current
• 1µA typical off-state supply current
• Output can be forced higher than input (off-state)
• Current limit
• Thermal shutdown
• 2.5V undervoltage lockout (UVLO)
• Open-load detection (MIC2505BN/M and MIC2506BN/M only)
• Open-drain fault flag
• 5ms (slow) turn-on and fast turnoff
• Logic-level control/enable input

Applications
• USB Power Distribution
• 3.3V and 5V power management
• PC Card card inrush limiting switch
• Hot plug-in power supplies
• Battery-charger circuits
