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 (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
2mm × 2mm thin DFN packages. The MIC2039 has an
operating junction temperature range of 40°C to +125°C.

Input: Power switch and logic supply input.
Ground: Input and output return pin.
Enable (Input): Logic compatible, enable control input that allows switch turn-
on/off. Do not leave the EN pin floating.
Fault Status Flag (Output): Active-low, open-drain output. A logic low state
indicates an overcurrent or thermal shutdown condition. An overcurrent
condition must last longer than tFAULT/ to assert FAULT/. A pull-up resistor
(10kΩ recommended) to an external supply is required.
Current Limit Set: Current limit adjust setting. Connect a resistor from this pin
to GND to set the current limit, but do not leave the ILIMIT pin floating.
Switch Output: Power switch output.
Exposed Pad: Exposed pad on bottom of package. Connect to electrical
ground for optimum thermal dissipation.
