Maxim Integrated MAX6823WUK Microprocessor Reset Circuit

The MAX6823WUK from Maxim Integrated is a compact, highly-reliable microprocessor (µP) supervisory circuit designed to maintain system integrity during power failures or unexpected events. This component is essential for applications that require precise monitoring of the power supply voltage to ensure proper system reset and operation.

The MAX6823WUK is housed in a space-saving 5-pin SOT23 package, making it an ideal choice for space-constrained applications. It's specifically engineered to monitor VCC in digital systems and provide a reset signal to the µP during power-up, power-down, and brown-out conditions. The reset signal ensures that the µP restarts in a known state, which is crucial for maintaining system reliability and performance.

One of the key features of the MAX6823WUK is its ability 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. This built-in delay allows the power supply and µP to stabilize before the system resumes operation, preventing any erratic behavior.

The device offers a variety of factory-trimmed VCC reset threshold voltages, allowing designers to select the appropriate version for their specific application needs. Additionally, the MAX6823WUK boasts low supply current requirements, making it suitable for use in portable and battery-operated equipment.

With its robust feature set, including a manual reset input, the MAX6823WUK provides system designers with a simple and effective way to enhance system reliability through active monitoring and control of the supply voltage. Whether used in computers, controllers, intelligent instruments, or portable devices, the Maxim Integrated MAX6823WUK is an indispensable component for any system that cannot afford unexpected resets or failures.

Overall, the MAX6823WUK from Maxim Integrated stands out as a high-quality, reliable solution for microprocessor reset applications, offering both versatility and ease of integration into a wide range of electronic systems.
