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 filtered. The MIC2026A/2076A are available in an 8-pin SOIC package.
