MICREL SEMICONDUCTOR  MIC2091-1YM5 TR  电源分配开关, 限流, 高压侧, 高电平有效, 1路输出, 5.5V, 0.1A, SOT-23-5

The is a high-side MOSFET Power Switch optimized for general-purpose 50 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 MIC2091 come in two versions like auto-retry current limit and output latch off on an over current fault.
