MIC2090/MIC2091

Current Limiting Power

Distribution Switches

General Description

Features

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. Typical applications for these

parts are for switching power in USB ports, portable

consumer items, camera and camcorder motor protection,

thermal printer head protection, and many other low

current-load switching applications.

• 1.8V to 5.5V supply voltage

• 790 mΩ typical R_DSONat 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 (t_{D_FAULT/}) eliminates false

assertions

The MIC2090 and MIC2091 come in two versions: auto-

retry current limit and output latch off on an over current

fault. The MIC2090 and MIC2091 are offered in a space

saving 5-pin SOT-23 package with an operating junction

temperature range of -40°C to +125°C.

• 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

Applications

• USB peripherals

• Camcorder

• DSC

• MP3/iPod

• SD protection

• USB low-power hub
