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.
All support documentation can be found on Micrel’s web
