Product Overview: MAX6383LT41D3+ from Maxim Integrated

The MAX6383LT41D3+ is a precision, low-power microprocessor (µP) supervisory circuit from Maxim Integrated designed to monitor power supplies in digital systems. This device ensures that the system's microprocessor is reset to a known state during power-up, power-down, or brown-out conditions. The MAX6383LT41D3+ is particularly well-suited for battery-powered electronics where extended battery life and reliability are critical.

Key Features

• Voltage Monitoring: The MAX6383LT41D3+ keeps a watchful eye on the system voltage, providing a reset signal to the host processor whenever the monitored voltage falls below the factory-set reset threshold of 4.125V. This feature is essential for preventing erratic system behavior caused by undervoltage conditions.
• Low Power Consumption: With its low quiescent current draw, this supervisory circuit helps to maximize battery life, making it an excellent choice for portable and energy-sensitive applications.
• Manual Reset Input: An additional manual reset input allows for an external trigger to initiate a system reset, providing designers with flexibility and control over system reset events.
• Reset Timeout: The device offers a fixed reset timeout period, ensuring that the system has ample time to return to a stable operating state before the reset signal is deasserted.

Applications

The MAX6383LT41D3+ is versatile and can be used across a wide range of applications, including:

• Portable/Battery-Powered Devices
• Embedded Systems
• Industrial Controllers
• Notebook Computers
• Medical Equipment

Package and Reliability
