MIC2039

High-Accuracy, High-Side, Adjustable

Current Limit Power Switch

General Description

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. 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 32ms delay that asserts low

during overcurrent or thermal-shutdown conditions.

The MIC2039 switches feature an adjustable output

current limit that is resistor programmable from 0.2A to

2.5A. The MIC2039 switch also offers a unique, Kickstart

feature that allows momentary high-current surges up to

the secondary current limit (I

LIMIT_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 2mm

× 2mm thin DFN packages. The MIC2039 has an

operating junction temperature range of

−40°C

to +125°C.
