MIC2026A/2076A
Dual-Channel Power Distribution Switch
General Description
Features
The MIC2026A and MIC2076A are high-side MOSFET
switches optimized for general-purpose power distribution
requiring circuit protection. The MIC2026A is particularly
well suited for USB applications.
The MIC2026A/2076A are internally current limited and
have thermal shutdown that protects the device and load.
The MIC2076A offers “smart” shutdown that reduces
current consumption in fault modes. When the MIC2076A
goes into thermal shutdown due to current limiting, the
output is latched off until the switch is reset. The
MIC2076A can be reset by removing the load, toggling the
enable input, or cycling VIN.
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 or
thermal shutdown conditions. Transient faults are internally
