Product Overview: MAX6383XR24D2-T by Maxim Integrated

The MAX6383XR24D2-T is a highly reliable, low-power microprocessor (μP) supervisory circuit designed by Maxim Integrated to monitor power supplies in digital systems. Its primary function is to ensure that the system's microprocessor is reset to a known state during power-up, power-down, or brown-out conditions. This tiny, robust device is a vital component for any system that requires a high degree of operational stability and reliability.

This supervisory circuit operates over a wide voltage range and offers factory-set reset threshold voltages, making it suitable for a variety of applications. The reset output of the MAX6383XR24D2-T is active low and comes in a push-pull configuration, which eliminates the need for an external pull-up resistor and helps to reduce component count and system complexity.

The MAX6383XR24D2-T features a precise reset threshold voltage of 2.40V, ensuring accurate monitoring of the power supply. The device's reset timeout period is fixed at 210ms, providing ample time for the system to stabilize before it is allowed to resume operation. This timeout period helps to prevent system errors that could occur if the power supply is not stable when the system attempts to operate.

Encapsulated in a small, 3-pin SC70 package, the MAX6383XR24D2-T is designed for space-constrained applications. Its small size makes it ideal for portable devices, where efficiency and compactness are critical. Despite its diminutive stature, it is robust enough to operate in a temperature range of -40°C to +125°C, making it suitable for industrial applications that may be exposed to harsh environments.

The device also features low supply current, drawing only 1.1μA of supply current at 1.2V, which is beneficial for battery-powered applications where power conservation is crucial.

In summary, the MAX6383XR24D2-T from Maxim Integrated is a versatile, low-power supervisory circuit that provides essential protection for digital systems. It is an excellent choice for designers looking for a reliable solution to enhance the operational stability of their microprocessor-based systems.
