Maxim Integrated MAX6365PKA31-T Microprocessor Supervisory Circuit

The Maxim Integrated MAX6365PKA31-T is a high-quality microprocessor (µP) supervisory circuit designed to monitor power supplies in µP and digital systems. It provides a significant line of defense against system failures caused by fluctuations and failures in the power supply. The MAX6365PKA31-T is an essential component for ensuring the reliable operation of microprocessor-based systems in various applications, including embedded systems, computers, and industrial control systems.

This supervisory circuit is particularly adept at providing maximum system stability by performing three key functions: it can reset a µP during power-up, power-down, and brownout conditions. The reset output remains asserted for a preset timeout period after V_CC has risen above the reset voltage threshold, ensuring that the µP starts up in a known state every time.

The MAX6365PKA31-T features a factory-trimmed reset threshold voltage, which is preset to 3.08V, suitable for operation with standard 3.3V power supplies. This precision voltage monitoring ensures that systems are protected from undervoltage conditions that could lead to unpredictable behavior. The device's active-low, push-pull RESET output remains asserted for a minimum of 140ms after V_CC has risen above the reset threshold, providing a reliable reset signal to the µP.

One of the key advantages of the MAX6365PKA31-T is its low power consumption. With a supply current of only 1.5µA, it is an excellent choice for portable and battery-powered applications where power efficiency is critical. The device is offered in a compact SOT23-8 package, making it an ideal solution for space-constrained applications.

Furthermore, the MAX6365PKA31-T operates over a wide temperature range of -40°C to +125°C, ensuring reliable performance across diverse environmental conditions. Its robust design and high-quality construction make it a trusted solution for system designers looking to enhance the reliability and stability of their power supply monitoring systems.

In summary, the Maxim Integrated MAX6365PKA31-T supervisory circuit is a highly reliable and efficient solution for monitoring the power supply in microprocessor systems, providing essential protection against power supply anomalies and ensuring the stable operation of critical electronic equipment.
