Maxim Integrated MAX6384XS31D3-T Microprocessor Reset Circuit

The MAX6384XS31D3-T is a highly reliable microprocessor (µP) supervisory circuit designed to monitor power supplies in digital systems. Manufactured by Maxim Integrated, this device provides excellent circuit reliability and low cost by eliminating external components and adjustments when used in systems with a 3.1V power supply.

This supervisory circuit ensures that the µP and its associated circuitry reset cleanly during power-up, power-down, or brown-out conditions. The MAX6384XS31D3-T features a factory-trimmed reset threshold, suitable for operation with a nominal supply voltage of 3.1 volts, making it an ideal choice for portable and battery-powered applications.

Key features of the MAX6384XS31D3-T include:

• Precision Factory-Set Reset Thresholds: The reset threshold is preset at the factory, ensuring accurate monitoring of the VCC without the need for external resistors or adjustments.
• Low Power Consumption: The device is designed for power-sensitive applications, with a low quiescent current that reduces the overall power consumption of the system.
• Manual Reset Input: A manual reset input is provided, allowing for a system reset to be initiated by a user or external signal.
• Reset Output: The reset output is available in either push-pull or open-drain configurations, providing flexibility in interfacing with other components in the system.
• Immunity to Short VCC Transients: The MAX6384XS31D3-T is designed to ignore short transients on the VCC line, thus preventing false resets from occurring.
• Temperature Range: This device operates over an extended temperature range, making it suitable for industrial applications.

The MAX6384XS31D3-T comes in a compact, surface-mount SOT-343 package, which is ideal for space-constrained applications. Its small size, combined with its robust feature set, makes it a versatile choice for system designers looking to enhance the reliability and performance of their power management systems.

Whether you are designing consumer electronics, portable devices, or complex digital systems, the MAX6384XS31D3-T provides a simple and effective solution for managing your system's power supply and ensuring stable operation across various conditions.
