MIC2090/MIC2091
Current Limiting Power
Distribution Switches
General Description
Features
The MIC2090 and MIC2091 are high-side MOSFET power
switches optimized for general-purpose 50mA or 100mA
low power distribution in circuits requiring over-current
limiting and circuit protection. Typical applications for these
parts are for switching power in USB ports, portable
consumer items, camera and camcorder motor protection,
thermal printer head protection, and many other low
current-load switching applications.
The MIC2090 and MIC2091 come in two versions: auto-
retry current limit and output latch off on an over current
fault. The MIC2090 and MIC2091 are offered in a space
saving 5-pin SOT-23 package with an operating junction
temperature range of -40 ° C to +125 ° C.
