MIC2026/2076

Dual-Channel Power Distribution Switch

Preliminary Information

General Description

Features

TheMIC2026andMIC2076arehigh-sideMOSFETswitches

optimized for general-purpose power distribution requiring

circuit protection.

• 140mΩ maximum on-resistance per channel

• 2.7V to 5.5V operating range

• 500mA minimum continuous current per channel

• Short-circuit protection with thermal shutdown

• Thermally isolated channels

• Fault status flag with 3ms filter

eliminates false assertions

• Undervoltage lockout

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

• Circuit breaker mode (MIC2076)

• Logic-compatible inputs

• Soft-start circuit

• Low quiescent current

The MIC2026/76 are internally current limited and have

thermal shutdown that protects the device and load.

The MIC2076 offers “smart” thermal shutdown that reduces

current consumption in fault modes. When a thermal shut-

down 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.

Both devices employ soft-start circuitry that minimizes inrush

current in applications where highly capacitive loads are

employed.

Pin-compatible with MIC2526

A fault status output flag is asserted during overcurrent and

thermal shutdown conditions. Transient faults are internally

filtered.

Applications

• USB peripherals

• General purpose power switching

• ACPI power distribution

• Notebook PCs

The MIC2026/76 are available in 8-pin DIP or 8-lead SOP.

• PDAs

• PC card hot swap
