Microchip | MIC2004-0.5YML-TR

MIC2004-0.5YML TR 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 2 mm x 2 mm MLF packages.
