Single-Channel Power Distribution Switch

Preliminary Information

General Description

Features

TheMIC2025andMIC2075arehigh-sideMOSFETswitches

optimized for general-purpose power distribution requiring

circuit protection.

• 140mΩ maximum on-resistance

• 2.7V to 5.5V operating range

• 500mA minimum continuous output current

• Short-circuit protection with thermal shutdown

• Fault status flag with 3ms filter eliminates false asser-

tions

The MIC2025/75 are internally current limited and have

thermal shutdown that protects the device and load. The

MIC2075 offers “smart” thermal shutdown that reduces cur-

rent consumption in fault modes. When a thermal shutdown

fault occurs, the output is latched off until the faulty load is

removed. Removing the load or toggling the enable input will

reset the device output.

• Undervoltage lockout

• Reverse current flow blocking (no “body diode”)

• Circuit breaker mode (MIC2075) reduces power

consumption

• Logic-compatible input

• Soft-start circuit

Both devices employ soft-start circuitry that minimizes inrush

current in applications where highly capacitive loads are

employed. A fault status output flag is provided that is

asserted during overcurrent and thermal shutdown condi-

tions.

• Low quiescent current

• Pin-compatible with MIC2525

Applications

• USB peripherals

TheMIC2025/75isavailableintheMM8™8-leadMSOPand

8-lead SOP.

• General purpose power switching

• ACPI power distribution

• Notebook PCs

• PDAs

• PC card hot swap
