General Description
MIC2003 and MIC2013 are high-side current limiting
devices, designed for power distribution applications in
PCs, PDAs, printers and peripheral devices.
MIC2003 and MIC2013 are thermally protected and will
shutdown should their internal temperature reach unsafe
levels, protecting both the device and the load, under
high current or fault conditions. Both devices are fully
self-contained, with the current limit value being factory
set to one of several convenient levels.
MIC2013 offers a unique new feature: Kickstart?,
which allows momentary high current surges to pass
unrestricted without sacrificing overall system safety.
MIC2003 and MIC2013 are excellent choices for USB
and IEEE 1394 (FireWire) applications or for any system
where current limiting and power control are desired.
The MIC2003 and MIC2013 are offered in space saving
6 pin SOT-23 and 2mm x 2mm MLF packages.
Data sheets and support documentation can be found
on Micrel’s web site at www.micrel.com.
