MIC2017 Datasheet | Micrel Semiconductor

Description The MIC2007 and MIC2017 are current limiting, highside power switches, designed for general purpose power distribution and control in PCs, PDAs, printers and other self-powered systems. The MIC2007 and MIC2017’s primary functions are .. current limiting and power switching. They are thermally protected and will shutdown should their internal temperature reach unsafe levels. This protects both the device and the load under high current or fault conditions. Features include: user adjustable output slew rate limiting, automatic load discharge and under voltage detection. Both devices offer user programmable current limiting thereby providing designers a continuous spectrum of current limits from 200m A to 2 Amps. The MIC2017 offers a unique new feature : Kickstart™, which allows momentary high current surges to pass unrestricted without sacrificing overall system safety. The MIC2007 and MIC2017 are excellent choices for USB and IEEE 1394 (Fire Wire) applications or for any system where current limiting and power control are desired. The MIC2007 and MIC2017 are offered in space saving 6-pin SOT-23 and 2mm x 2mm MLFTM packages.
