MCP6546T-I/OT

MCP6546T-I/OT is an open-drain output sub-microamp single comparator. The output is open-drain and is capable of driving heavy DC or capacitive loads. This comparator is optimized for low power, single-supply application with greater than rail-to-rail input operation. The output limits supply current surges and dynamic power consumption while switching. It can also be used as a wired-OR logic. The internal Input hysteresis eliminates output switching due to internal noise voltage, reducing current draw. Typical application includes laptop computers, mobile phones, metering systems, hand-held electronics, RC timers, alarm and monitoring circuits, windowed comparators, multi-vibrators.
