General Description

The MIC2005 and MIC2015 are current limiting, high-

side power switches, designed for general purpose

power distribution and control in PCs, PDAs, printers

and other self-powered systems.

The MIC2005 and MIC2015’s primary functions are

current limiting and power switching. They are thermally

protected and will shut down should their internal

temperature reach unsafe levels, protecting both the

device and the load, under high current or fault

conditions.

Features include fault reporting, with fault blanking to

eliminate noise-induced false alarms, output slew rate

limiting and under voltage detection. Both devices are

fully self-contained, with the current limit value being

factory set to one of several convenient levels.

The MIC2015 offers a unique new feature: Kickstart

which allows momentary high current surges to pass

unrestricted without sacrificing overall system safety.

The MIC2005 and MIC2015 are excellent choices for

USB and IEEE 1394 (FireWire) applications or for any

system where current limiting and power control are

desired.

The MIC2005 and MIC2015 are offered in space saving

6 pin SOT-23 and 2mm x 2mm MLF packages.
