General Description

The MIC2025 and MIC2075 are high-side MOSFET switches

optimized for general-purpose power distribution requiring

circuit protection.

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.

Both devices employ soft-start circuitry that minimizes inrush

current in applications where highly capacitive loads are em-

ployed. A fault status output ﬂag is provided that is asserted

during overcurrent and thermal shutdown conditions.

The MIC2025/75 is available in the MM8® 8-lead MSOP

and 8-lead SOP.
