General Description

The MIC2026 and MIC2076 are high-side MOSFET

switches optimized for general-purpose power distribution

requiring circuit protection.

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 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.

Both devices employ soft-start circuitry that minimizes

inrush current in applications where highly capacitive loads

are employed.

A fault status output flag is asserted during overcurrent

and thermal shutdown conditions. Transient faults are

internally filtered.

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