MIC2039 Datasheet (Micrel Semiconductor) - Adjustable Current Limit Power Switch

MIC2039, Adjustable Current Limit Power Switch

The MIC2039 is a high-side MOSFET power distribution switch providing increased system reliability by using 5% current-limit accuracy.

The MIC2039 has an operating input voltage range from 2.5V to 5.5V, is internally current limited, and has thermal shutdown to protect the device and system.
