MCP6541/1R/1U/2/3/4 is a comparator with low quiescent current, wide voltage range, and output that can drive heavy loads. It is suitable for laptops, mobile phones, and other devices.
The MCP6541/1R/1U/2/3/4 family from Microchip provides single, dual and quad push‑pull comparators. They feature low quiescent current (600 nA typical per comparator), rail‑to‑rail input operation, and CMOS/TTL‑compatible outputs capable of driving heavy loads.
The device operates from a single supply of 1.6 V to 5.5 V, supports industrial (‑40 °C to +85 °C) and extended (‑40 °C to +125 °C) temperature ranges, and offers typical propagation delay of 4 µs and internal hysteresis of 3.3 mV. Detailed electrical, AC, and temperature characteristics are provided in the datasheet.
