General Description
The MIC2090 and MIC2091 are high-side MOSFET power switches optimized for general purpose 50 m A or 100 m A low power distribution in circuits that require overcurrent limiting and circuit protection. Typical applications for these parts include switching power in USB ports, portable consumer...
