Maxim Integrated MAX6384XS16D3+T Microprocessor Reset Circuit

The Maxim Integrated MAX6384XS16D3+T is a highly reliable microprocessor (µP) supervisory circuit designed to monitor power supplies in digital systems. It provides a significant layer of protection by ensuring that the µP and its peripherals are reset properly during power-up, power-down, or brown-out conditions. This device is part of Maxim's series of low-power, low-voltage reset circuits that are essential for maintaining the integrity of digital systems.

With a factory-set reset threshold voltage of 1.575V, the MAX6384XS16D3+T is tailored to operate with a specific range of power supplies, ensuring compatibility and straightforward integration into system designs. When the monitored voltage falls below the reset threshold, the reset output is asserted, which remains active for a minimum reset timeout period of 280ms after the voltage rises above the reset threshold, giving the system ample time to stabilize.

The compact form factor of the MAX6384XS16D3+T comes in a 4-pin SC70 package, making it an ideal solution for space-constrained applications. This tiny footprint does not compromise its performance; it boasts a low supply current of only 1.2µA, making it suitable for portable and battery-operated devices where power efficiency is critical.

Furthermore, this supervisory circuit features an active-low, push-pull reset output. The push-pull configuration eliminates the need for an external pull-up resistor, simplifying design and reducing component count. The active-low signal ensures compatibility with a wide range of microprocessors and other digital systems that require an active-low reset input.

The MAX6384XS16D3+T operates over an extended temperature range of -40°C to +125°C, making it versatile for use in various environments, from industrial to automotive applications. Maxim Integrated's commitment to quality and reliability is reflected in this product, which undergoes rigorous testing and quality control measures.

In summary, the Maxim Integrated MAX6384XS16D3+T is a robust and efficient solution for µP system stability, offering a precise voltage monitoring capability, low power consumption, and a small package size, making it an excellent choice for a wide range of applications.
