Microchip Technology MIC2042-1YM-TR

Description
The MIC2042 and MIC2043 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 feature programmable current limiting and thermal shutdown for device and load protection. A fault status output detects overcurrent and thermal shutdown conditions. Soft-start circuitry minimizes inrush current in applications with capacitive loads. The output slew rate can be adjusted for tighter control over inrush current during startup.
