MCP6566T-E/OT: Microchip's High-Speed, Low-Power Push-Pull Output Comparator

In the realm of modern electronic design, the need for components that deliver both speed and efficiency is paramount. Addressing this critical requirement, Microchip Technology's MCP6566T-E/OT stands out as a high-performance, single-channel comparator engineered for a wide array of applications. This device masterfully combines high-speed operation with remarkably low power consumption, a combination that is often difficult to achieve.

A defining feature of the MCP6566T-E/OT is its push-pull output stage. Unlike comparators with open-drain outputs that require an external pull-up resistor, this integrated push-pull architecture provides rail-to-rail output swings, capable of directly driving loads—both digital and analog—with minimal external components. This not only simplifies board design and saves space but also enhances switching speed, as the active pull-up and pull-down transistors ensure swift rise and fall times.

Performance is at the core of this comparator. With a propagation delay of just 450 ns while consuming a mere 20 µA of supply current per comparator, the MCP6566T-E/OT offers an exceptional speed-to-power ratio. This makes it an ideal choice for battery-powered and portable devices where every microwatt counts, without sacrificing the necessary response time for signal detection or threshold crossing.

The device operates over a broad supply voltage range from 1.6V to 5.5V, providing designers with immense flexibility for use in both low-voltage microcontroller-based systems and traditional 5V circuits. Its input common-mode range extends beyond the supply rails by 200 mV, allowing it to handle signals that swing slightly above and below the power supply voltages. Furthermore, it is designed to be robust, featuring ESD protection and a -40°C to +125°C extended temperature range, ensuring reliable operation in harsh industrial and automotive environments.

Typical applications span from simple voltage monitoring and window comparators to more complex systems like portables, battery management, and motor control circuits. Its small SOT-23-5 package is perfect for space-constrained PCB layouts.

ICGOOODFIND: The MCP6566T-E/OT is a superior choice for designers seeking a compact, versatile, and high-efficiency comparator. Its push-pull output eliminates the need for external pull-up resistors, its ultra-low quiescent current maximizes battery life, and its high-speed performance ensures system responsiveness. This blend of features makes it an excellent component for optimizing both the performance and power budget of modern electronic designs.
