Features & Applications

The MIC2009A-1YM6 TR is a current limiting, high-side power switches, designed for general purpose power distribution and control in PCs, PDAs, printers and other self-powered systems.

The MIC2009A-1YM6 TR’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: fault reporting, with fault blanking to eliminate noise-induced false alarms; 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 MIC2009 and MIC2019 are excellent choices for USB and IEEE 1394 (FireWire) applications or for any system where current limiting and power control are desired. The MIC2009 and MIC2019 are offered in space saving 6-pin SOT-23 and 2 mm x 2 mm MLF packages.
