MIC2033
High-Accuracy, High-Side, Fixed
Current Limit Power Switch
General Description
The MIC2033 is a high-side MOSFET power distribution
switch providing increased system reliability utilizing 5%
current limit accuracy.
The MIC2033 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 MIC2033
is offered with either active-high or active-low logic level
enable input controls, has an open drain fault status output
flag with a built-in 32ms delay that asserts low during over
current or thermal shutdown conditions.
The MIC2033 is available in several different fixed current
limit options: 0.5A, 0.8A, 1A, and 1.2A. A capacitor
adjustable soft-start circuit minimizes inrush current in
applications where high capacitive loads are used.
The MIC2033 is offered in both 6-pin SOT-23 and 6-pin
2mm x 2mm thin DFN packages. The MIC2033 has an
operating junction temperature range of
40°C
to +125°C.
