Maxim Integrated MAX6801UR26D3+T Microprocessor Reset Circuit

The MAX6801UR26D3+T is a compact, highly reliable microprocessor (µP) supervisory circuit designed by Maxim Integrated to monitor power supplies in µP and digital systems. It provides a significant level of system reliability through its reset function, ensuring that the µP boots up in a known state every time. This is particularly crucial for systems that require consistent operation and performance without manual intervention.

This device is specifically engineered to maintain system integrity by monitoring the VCC supply voltage. It operates by asserting a reset signal whenever the VCC supply voltage falls below the factory-set reset threshold level. The reset output remains asserted for a preset timeout period after VCC has risen above the reset threshold, providing a stable system reset. The reset threshold for the MAX6801UR26D3+T is precisely set at 2.63V, making it suitable for low-voltage applications.

The MAX6801 comes in a compact SOT-23 package, which is ideal for space-constrained applications. Its small footprint and low power consumption make it perfect for portable and battery-operated devices. The device is also characterized for operation over a wide temperature range of -40°C to +125°C, ensuring reliable operation in diverse environmental conditions.

One of the key features of the MAX6801UR26D3+T is its low supply current of 5.5µA (typical), which contributes to the overall energy efficiency of the system it is a part of. This makes it an excellent choice for power-sensitive applications. Additionally, the device includes a debounced manual reset input, which provides a manual override capability, further enhancing the system's robustness and flexibility.

The product comes in tape and reel packaging, denoted by the '+T' suffix, which facilitates automated assembly processes, making it a convenient choice for mass production environments. With its high precision, low power consumption, and small size, the MAX6801UR26D3+T is an essential component for ensuring stable operation in a wide range of electronic systems, from consumer electronics to industrial controls.

Overall, the Maxim Integrated MAX6801UR26D3+T offers a simple and efficient solution for system reset management, making it a valuable asset for maintaining the health and functionality of microprocessor-based systems.
