MIC2039 - High-Accuracy, High-Side, Adjustable Current Limit Power Switch
Docket ↓MIC2039
High-Accuracy, High-Side, Adjustable
Current Limit Power Switch General Description Features 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 Г— 2mm thin DFN packages. The MIC2039 has an ...
