Maxim Integrated MAX6315US31D1+T Microprocessor Reset Circuit

The MAX6315US31D1+T from Maxim Integrated is a compact, highly reliable microprocessor (µP) supervisory circuit designed to monitor power supplies in µP and digital systems. It provides a significant level of system reliability through its ability to reset a µP during power-up, power-down, and brownout conditions, ensuring that your system operates smoothly under various power scenarios.

This device comes in a small 4-pin SOT-143 package, making it an ideal choice for space-constrained applications. The MAX6315 features a preset reset threshold voltage of 3.1V, which is suitable for 3.3V powered systems, ensuring that the µP resets are accurately triggered to prevent system errors and data corruption.

One of the key features of the MAX6315US31D1+T is its immunity to short VCC transients, which guarantees that the reset output will remain in the correct state during brief power glitches. This is critical for maintaining system stability and preventing unintended system resets that could lead to data loss or corruption.

The device offers a reset timeout period of 140ms (min), providing ample time for the µP to stabilize and initialize properly before starting its operation. This timeout duration is carefully designed to accommodate a wide range of µP and system requirements.

Moreover, the MAX6315US31D1+T consumes low supply current, typically 1µA, making it an energy-efficient choice for portable and battery-operated devices where power conservation is essential. This low power consumption extends battery life and reduces overall power requirements for the system.

With its wide operating temperature range from -40°C to +85°C, the MAX6315US31D1+T is versatile and can be used in diverse environments, from industrial to consumer applications.

In summary, the Maxim Integrated MAX6315US31D1+T is a robust µP supervisory circuit that provides essential protection features for digital systems. Its small package, precise reset threshold, transient immunity, low power consumption, and wide operating temperature range make it an excellent choice for ensuring the reliable operation of your electronic systems.
