Microchip High Side 1, Current Limiting Distribution Power Switch IC 5-Pin, SOT-23

The MIC2090 and MIC2091 are high-side MOSFET power switches optimized for general-purpose 50mA or 100mA low power distribution in circuits requiring over-current limiting and circuit protection.

• 1.8V to 5.5V supply voltage
• 790 mΩ typical RDSON at 3.3V
• MIC2090 is rated for 50mA minimum continuous current
• MIC2091 is rated for 100mA minimum continuous current
• Reverse current blocking (OGI)
• 20ns super fast reaction time to hard short at output
• 10ms fault flag delay (tD_FAULT/) eliminates false assertions
• Auto-retry overcurrent and short-circuit protection (-1 version)
• Latch-off on current limit (-2 version)
• Thermal shutdown
• Fault status flag indicates: over-current, over-temperature, or UVLO
• Under-voltage lockout (UVLO)
• Low quiescent current
