The MIC2026A is particularly well suited for USB applications. The MIC2026A/76A 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...
