Maxim Integrated MAX6327XR29+T Microprocessor Supervisory Circuit

The MAX6327XR29+T is a highly precise, low-power, microprocessor (µP) supervisory circuit designed by Maxim Integrated to monitor power supplies in µP and digital systems. This supervisory IC provides excellent circuit reliability and low cost by eliminating external components and adjustments when used in systems that require voltage monitoring.

One of the key features of the MAX6327XR29+T is its ability to provide a reset signal to the µP during power-up, power-down, and brown-out conditions. With factory-trimmed reset threshold voltages, the device ensures that the system resets are accurate and consistent. The reset output remains operational with VCC as low as 1.2V, which is crucial for low-voltage applications.

This component has an impressive low supply current of 5µA (typical), making it an ideal choice for portable and battery-operated equipment where power conservation is a priority. The reset output is available with a choice of active-high, active-low, push-pull, or open-drain configurations, providing designers with flexibility in system design.

The MAX6327XR29+T operates over a wide temperature range of -40°C to +125°C, which allows it to be used in environments with extreme temperature conditions. The device comes in a compact, 3-pin SC70 package, which is suitable for space-constrained applications.

With a preset reset threshold voltage of 2.93V, the MAX6327XR29+T is tailored for applications that require precise voltage monitoring. For systems that need a different reset threshold, Maxim Integrated offers a variety of factory-set voltages to choose from, ensuring that designers can find the right fit for their specific requirements.

Overall, the MAX6327XR29+T is a robust and reliable solution for system monitoring, providing the necessary protection for µPs by ensuring that all the power-up, power-down, and voltage sag requirements are met. Its integration into a system helps to increase the reliability and performance of the overall application.
