Microchip MIC2091-1YM5-TR, 1High Side, 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
