Features & Applications

The MIC2003-1.2YM5 TR is a current limiting, high-side power switche that are designed for general purpose power distribution and control in PCs, PDAs, printers and other self-powered systems.

The MIC2003 and MIC2013’s main function is current limiting. 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. Both devices are fully self-contained, with the current limit value being factory set to one of several convenient levels. The MIC2013 offers a unique new feature: Kickstart™, which allows momentary high current surges to pass unrestricted without sacrificing overall system safety. The 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 2 mm x 2 mm MLF packages.
