Maxim Integrated MAX6337US20D3+T Microprocessor Reset Circuit

The Maxim Integrated MAX6337US20D3+T is a highly reliable and robust microprocessor (µP) supervisory circuit designed to monitor power supplies in µP and digital systems. It provides a significant layer of protection by ensuring that the µP boots up in a known state. This is particularly crucial for systems that require stable and reliable operation under various conditions, such as industrial controls, embedded systems, and portable consumer electronics.

This device is designed to assert a reset signal whenever the VCC supply voltage falls below a preset threshold, keeping it asserted for at least 140ms after VCC has risen above the reset threshold. The reset output is available in both active-high and active-low configurations, making the MAX6337US20D3+T versatile for different types of microprocessor systems. The reset threshold for this particular model is set at 2.0V, which is ideal for systems operating at lower voltages.

One of the key features of the MAX6337US20D3+T is its low supply current draw, typically just 1.2µA, which is especially beneficial for battery-powered applications where power conservation is critical. This device also offers a manual reset input, allowing for a system reset to be triggered with an external pushbutton or logic signal.

The MAX6337US20D3+T comes in a compact SOT-323 package, making it suitable for space-constrained applications. It is available in a tape-and-reel format denoted by the "+T" suffix, which facilitates automated pick-and-place manufacturing processes.

In summary, the Maxim Integrated MAX6337US20D3+T is a feature-rich, low-power microprocessor supervisory circuit that provides critical monitoring of system voltage. Its small size, low power consumption, and reset management capabilities make it an excellent choice for enhancing the reliability and performance of a wide range of electronic systems.
