Dual-Channel Power Distribution Switch
Preliminary Information
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 shut-
down 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-lead SOP.
