MIC2025/2075 Micrel, Inc. MIC2025/2075
Single-Channel Power Distribution Switch MM8В® General Description Features 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 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 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. 140mΩ maximum on-resistance
2.7V to 5.5V operating range
