3.General Description
The MIC2026 and MIC2076 are high-side MOSFETswitches optimized for general-purpose powerdistribution that requires circuit protection.
The MIC2026/76 are internally current limited and havethermal shutdown that protects the device and load.
The MIC2076 offers “smart” thermal shutdown thatreduces current consumption in fault modes. When athermal shutdown fault occurs, the output is latched offuntil the faulty load is removed. Removing the load ortoggling the enable input will reset the device output.
Both devices employ soft-start circuitry that minimizesinrush current in applications where highly capacitiveloads are employed.
A fault status output flag is asserted during overcurrentand thermal shutdown conditions. Transient faults areinternally filtered.
The MIC2026/76 are available in an 8-pin SOICpackage
