Overview

The MCP6544-E/P is a quad-channel, sub-microamp comparator designed for ultra-low-power applications. It operates from a single supply as low as 1.6V and features internal hysteresis to ensure stable switching in noisy environments. The push-pull output stage simplifies interfacing by eliminating the need for external pull-up resistors.

Why Choose This Part

This comparator offers a significant power advantage with less than 1 microamp of quiescent current per channel while operating across a wide temperature range of -40 to 125 degrees Celsius. The integrated 6.5mV hysteresis prevents multiple transitions due to input noise, and the push-pull output is compatible with both TTL and CMOS logic levels.

Applications

Battery-Powered Monitoring
Utilizes the extremely low 0.6 microamp typical quiescent current to extend battery life in portable security or environmental sensors.
RC Timer Circuits
Leverages the high-impedance CMOS inputs and rail-to-rail output for precise timing applications in low-frequency oscillators.
Windowed Comparators
Uses the four integrated elements to create voltage window detectors for over/under-voltage protection in handheld electronics.
Zero-Crossing Detectors
Provides reliable signal threshold detection for low-speed communication or metering systems.
