MIC2044/45

The MIC2044 and MIC2045 are high-side MOSFET switches optimized for general purpose power distribution applications that require circuit protection. MIC2044 and MIC2045 switch up to 5.5V and as low as 0.8V while offering both programmable current limiting and thermal shutdown to protect the device and the load. A fault status output is provided to indicate overcurrent and thermal shutdown fault conditions. Both MIC2044 and MIC2045 employ soft-start circuitry to minimize the inrush current in applications that employ highly capacitive loads. Additionally, for tighter control over inrush current during start up, the output slew-rate may be adjusted by an external capacitor.
