Device Overview

Summary

The MIC2073/2074 are high-side MOSFET switches optimized for general-purpose power distribution requiring circuit protection. The MIC2073/2074 are internally current limited and have thermal shutdown for protecting the device and load. The MIC2074 offers "smart" shutdown that reduces current consumption in fault mode. When a fault occurs due to thermal shutdown, the output is latched off. The MIC2074 output will be reset, enabling the output, either by removing the load or toggling the ENABLE pin. 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 MIC2073/2074 are available in an 8-pin SOIC.
