The Microchip Technology Inc. MCP6546/6R/6U/7/8/9 family of comparators is designed for low-power, single-supply applications. These comparators offer open-drain outputs capable of driving heavy DC or capacitive loads, and feature rail-to-rail input operation and low quiescent current. They are suitable for laptop computers, mobile phones, metering systems, and other portable electronics requiring precise voltage comparison and level shifting.
