Microchip | MIC2018YML-TR

The MIC2018YML TR is a current limiting, high-side power switch, designed for general purpose power distribution and control in PCs, PDAs, printers and other self-powered systems.

The MIC2008 and MIC2018’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 and under voltage detection. Both devices offer user programmable current limiting thereby providing designers a continuous spectrum of current limits from 200 mA to 2 Amps. The MIC2018 offers a unique new feature: Kickstart™, which allows momentary high current surges to pass unrestricted without sacrificing overall system safety. The MIC2018YML TR is an excellent choices for USB and IEEE 1394 (FireWire) applications or for any system where current limiting and power control are desired. The MIC2018YML TR is offered in space saving 2 mm x 2 mm MLF^TM packages.
