General Description

The MIC2090 and MIC2091 are high-side MOSFET power switches optimized for general purpose 50 mA or 100 mA 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 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 overcurrent fault.

Overview

MIC2090/1 Current-Limiting Power Distribution Switches.
