MIC2040/2041

Single Channel Low Voltage Power Distribution Switch

General Description

Features

The MIC2040 and MIC2041 are high side MOSFET switches

optimizedforgeneralpurposepowerdistributionapplications

that require circuit protection. The 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 in order to detect

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, the MIC2040/41 is suited for multi-port USB

applications to satisfy upstream/downstream power require-

ments.

• 75mΩ max. on-resistance

• 0.8V to 5.5V operating range

• Adjustable current limit

• Up to 1.5A continuous output current

• Short circuit protection with thermal shutdown

• Circuit breaker mode (MIC2041)

• Fault status flag

• Undervoltage lockout

• Output MOSFET reverse current flow block when

disabled

• Very fast reaction to short-circuits

• Low quiescent current

The MIC2041 features a auto-reset circuit breaker mode that

lasting more than 28ms. The output is reset by removing or

reducing the load.

Applications

• Docking stations

• Notebook PCs

• PDAs

• Board hot swap

• RAID controllers

• USB peripherals

• ACPI power distribution
