General Description

The MIC20XX 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 (see MIC20XX Family Package Types and the MIC20XX Family Member Functionality table).

MIC20XX 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 high-current or fault conditions.
