General Description

The MIC2039 is a high-side MOSFET power distribution switch that provides 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. The MIC2039 is offered with either active-high or active-low logic level enable input controls. It has an open drain fault status output flag with a built-in 32 ms delay that asserts low during overcurrent or thermal-shutdown conditions.

The MIC2039 features an adjustable output current limit that is resistor-programmable from 0.2A to 2.5A. The MIC2039 also offers a unique, kickstart feature that allows momentary high-current surges up to the secondary current limit (ILIMIT_2nd) during startup or while operating in steady-state. This is useful for charging loads with high inrush currents, such as capacitors. After an overcurrent condition is established, these switches enter into a constant current-limit mode unless the die temperature exceeds the thermal-shutdown specification.

The MIC2039 is available in 6-pin SOT-23 and 6-pin 2 mm x 2 mm thin DFN packages. The MIC2039 has an operating junction temperature range of –40°C to +125°C.
