Maxim Integrated's MAX6383XR23D3+T Microprocessor Reset Circuit

The MAX6383XR23D3+T is a compact, high-precision microprocessor (μP) supervisory circuit designed to monitor power supplies in digital systems. Manufactured by Maxim Integrated, a renowned leader in analog and mixed-signal engineering, this component ensures reliable operation of microprocessor-based systems by providing a reset signal whenever the VCC supply voltage drops below a preset threshold. The MAX6383XR23D3+T is an essential device for maintaining system integrity during power-up, power-down, and brown-out conditions.

This supervisory circuit is available in a tiny, 3-pin SC70 package, making it an ideal solution for space-constrained applications. It offers a factory-set reset threshold voltage of 2.3V, which is tailored to the specific needs of 2.5V-powered systems. With its precision voltage monitoring and low supply current, the MAX6383XR23D3+T is optimized for portable and battery-operated devices.

Key features of the MAX6383XR23D3+T include:

• High Accuracy: This device maintains a ±1.5% reset threshold accuracy over the entire operating temperature range, ensuring dependable system performance.
• Low Power Consumption: The circuit is designed for minimal power usage, with a typical supply current of only 1.2μA, which is crucial for extending battery life in portable applications.
• Manual Reset Input: An additional feature is the manual reset input, which allows for a system reset to be triggered by an external event or user intervention, adding an extra layer of system control.
• Immune to Short VCC Transients: The device includes an integrated debounce circuit that filters out short-duration VCC transients, preventing false resets and enhancing system reliability.
• Extended Temperature Range: The MAX6383XR23D3+T operates over an extended temperature range of -40°C to +125°C, making it suitable for industrial applications.

This supervisory circuit is offered in a lead-free, RoHS-compliant package, reflecting Maxim Integrated's commitment to environmentally friendly manufacturing practices. The MAX6383XR23D3+T is a testament to Maxim's dedication to providing innovative, high-quality products that meet the stringent requirements of modern electronic systems.
