Microchip Technology MIC2045-1YTS

Description
The MIC2044 and MIC2045 are high-side MOSFET switches designed for power distribution applications requiring circuit protection. They operate within a voltage range of 0.8V to 5.5V and offer programmable current limiting and thermal shutdown to safeguard the device and load. A fault status output indicates overcurrent and thermal shutdown conditions. Soft-start circuitry minimizes inrush current in applications with capacitive loads. Additionally, an external capacitor can adjust the output slew rate for tighter control over inrush current during startup.
