Maxim Integrated MAX6736XKVRD3 Microprocessor Supervisory Circuit

The MAX6736XKVRD3 is a high-quality microprocessor (µP) supervisory circuit developed by Maxim Integrated, designed to monitor power supplies in digital systems. It ensures that the microprocessor is reset to a known state during power-up, power-down, and brown-out conditions. The device is particularly suitable for portable and battery-powered equipment due to its low power consumption and small size.

This supervisory circuit offers several key features that make it an essential component for system reliability. One of the most critical functions is the adjustable power-on reset (POR) timeout delay, which allows designers to set the duration of the reset signal according to their system requirements. The device also provides a manual reset input, enabling an external signal to initiate a system reset.

The MAX6736XKVRD3 operates over a wide voltage range, from 1.6V to 5.5V, making it versatile for various applications. It boasts a low supply current, which is essential for extending battery life in portable applications. The circuit comes in a compact SOT-23 package, which is ideal for space-constrained applications.

Additional features include a debounced manual reset input, a reset output stage that can be configured as push-pull or open-drain, and a factory-trimmed reset threshold voltage. This precision ensures reliable operation under varying conditions and reduces the need for external components, simplifying the design process.

The MAX6736XKVRD3 is designed with the robustness expected of Maxim Integrated products. It includes over-temperature protection and is specified over the extended -40°C to +125°C temperature range, which makes it suitable for industrial applications where temperature extremes are a concern.

In summary, the Maxim Integrated MAX6736XKVRD3 microprocessor supervisory circuit is an excellent choice for designers who need a reliable, flexible, and space-efficient solution to ensure system stability and integrity. Whether used in portable devices, consumer electronics, or industrial systems, this supervisory circuit helps maintain the correct operation of the microprocessor, thereby enhancing the overall performance and reliability of the application it serves.
