The MIC2009 family of switches are current limiting, high-side power switches, designed for general purpose power distribution and control in digital televisions (DTV), printers, set top boxes (STB), PCs, PDAs, and other peripheral devices. MIC2009 family’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 highcurrent or fault conditions. Features include fault reporting, fault blanking to eliminate noise-induced false alarms, output slew rate limiting, under voltage detection, automatic-on output, and enable pin with choice of either active low or active high enable. The FET is self-contained, with a fixed- or user-adjustable current limit. The MIC2009 family is ideal for any system where current limiting and power control are desired. The MIC2009 family is offered, depending on the desired features, in a space-saving 5-pin SOT-23, 6-pin SOT-23, and 2mm x 2mm MLF® packages.
