General Description
MIC2004 and MIC2014 are current limiting, high-side
power switches, designed for general purpose power
distribution and control in PCs, PDAs, printers and other
self-powered systems.
MIC2004 and MIC2014’s primary functions are current
limiting and power switching. They 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. MIC2004/2014 feature a load discharge FET
which ensures any output capacitance is discharged
when the switch is turned off. This is particularly useful
in hot-swapping applications where ‘cold’ connections
are desired.
Both devices are fully self-contained, with the current
limit value being factory set to one of several convenient
levels.
MIC2014 offers a unique new feature: Kickstart
which allows momentary high current surges to pass
unrestricted without sacrificing overall system safety.
MIC2004 and MIC2014 are excellent choices for USB
and IEEE 1394 (FireWire) applications or for any system
where current limiting and power control are desired.
The MIC2004 and MIC2014 are offered in space saving
6 pin SOT-23 and 2mm x 2mm MLF packages.
