MIC2044/2045

Single Channel, High Current, Low Voltage,

Protected Power Distribution Switch

General Description

Features

TheMIC2044andMIC2045arehigh-sideMOSFETswitches

optimizedforgeneralpurposepowerdistributionapplications

that require circuit protection. These devices switch up to

5.5V and as low as 0.8V while offering both programmable

current limiting and thermal shutdown to protect the device

and the load. A fault status output is provided to indicate

overcurrent and thermal shutdown fault conditions. Both

devices employ soft-start circuitry to minimize the inrush

current in applications that employ highly capacitive loads.

Additionally, fortightercontroloverinrushcurrentduringstart

up, the output slew-rate may be adjusted by an external

capacitor.

• 30mΩ maximum on-resistance

• 0.8V to 5.5V operating range

• Adjustable current limit

• Up to 6A continuous output current

• Short circuit protection

• Very fast reaction to short circuits

• Thermal shutdown

• Adjustable slew-rate control

• Circuit breaker mode (MIC2045)

• Fault status flag

• Power-Good detection

• Undervoltage lockout

• No reverse current flow through the switching MOSFET

when OFF or disabled

• Low quiescent current

TheMIC2045featuresaauto-resetcircuitbreakerthatlatches

the output OFF upon detecting an overcurrent condition

lasting more than 32ms. The output is reset by removing or

reducing the load.
