Product Overview: MAX6376XR31 from Maxim Integrated

The MAX6376XR31 is a precision, low-power microprocessor (µP) supervisory circuit designed to monitor power supplies in µP and digital systems. It provides excellent circuit reliability and low cost by eliminating external components and adjustments when used in systems with a 3.1V power supply voltage.

This supervisory circuit from Maxim Integrated ensures that the µP starts up in a known state. It achieves this by monitoring the power supply voltage and maintaining a reset output until that voltage reaches a stable and accurate threshold. The reset signal remains asserted for a minimum timeout period after the supply voltage exceeds the threshold, providing a guaranteed reset duration and allowing the power supply and µP to stabilize.

Key Features

• Voltage Monitoring: The MAX6376XR31 precisely monitors the 3.1V power supply, providing a high level of system reliability.
• Low Power Consumption: With its low power draw, this device is ideal for power-sensitive applications.
• Reset Timeout: A minimum reset timeout period ensures that the system has ample time to stabilize after a power disturbance.
• Manual Reset Input: The device includes a manual reset input that allows for a system reset without the need to cycle the power.
• Compact Package: Available in a small SOT23 package, the MAX6376XR31 saves space on the PCB, making it suitable for compact systems.

Applications

The MAX6376XR31 is versatile and can be used in a variety of applications where accurate monitoring of the power supply voltage is critical. These include:

• Portable/Battery-Powered Equipment
• Embedded Systems
• Computers and Servers
• Data Storage Equipment
• Industrial Controllers

With its combination of features, the MAX6376XR31 from Maxim Integrated is an essential component for ensuring the stability and reliability of electronic systems. Its ability to prevent code execution errors during power-up, power-down, and brownout conditions makes it a valuable addition to any design requiring a 3.1V power supply monitoring solution.
