Microchip MCP6547-E/SN: A Dual Comparator with Open-Drain Outputs for Flexible Design

The Microchip MCP6547-E/SN is a dual-channel comparator featuring open-drain outputs, designed to offer designers enhanced flexibility and performance in a wide array of applications. This device operates over a broad voltage range from 1.6V to 5.5V, making it suitable for both low-voltage and standard systems, including battery-powered and portable electronics. With an ultra-low supply current of just a few microamps per comparator, it is an excellent choice for power-sensitive designs where energy efficiency is critical.

A key feature of the MCP6547-E/SN is its open-drain output configuration, which allows the output to be easily pulled up to a voltage higher than the supply voltage of the comparator itself. This provides significant interface flexibility, enabling direct connection to systems operating at different logic levels. Each output can be independently controlled, simplifying the design of wired-AND logic or level translation circuits. Additionally, the device includes internal hysteresis, which improves noise immunity and ensures stable operation in electrically noisy environments without requiring external components.

The MCP6547-E/SN is available in the compact 8-pin SOIC package, making it ideal for space-constrained PCB layouts. It is characterized for extended temperature ranges (-40°C to +125°C), ensuring reliability in industrial and automotive applications. Common uses include window comparators, voltage monitoring, signal conditioning, and threshold detection.
