MAX6316LUK29CY+T Microprocessor Reset Circuit

The MAX6316LUK29CY+T is a highly reliable microprocessor (µP) supervisory circuit designed by Maxim Integrated to monitor power supplies in µP and digital systems. It provides a significant level of system reliability through its ability to reset a microprocessor during power-up, power-down, and brown-out conditions, ensuring that the µP starts up in a known state every time.

This supervisory circuit is particularly suitable for portable, battery-powered applications due to its low power consumption and compact SOT-23 packaging. With an active-low reset output, the MAX6316LUK29CY+T maintains system integrity by holding the µP in a reset state until the system voltage has stabilized at the correct operating level and for a specified period after that, to ensure a reliable system startup.

Key Features:

• Precision Voltage Monitoring: The MAX6316LUK29CY+T monitors the system voltage and actively manages the reset function, ensuring that the µP does not operate under unpredictable conditions that could lead to system errors.
• Factory-Set Reset Threshold: The reset threshold is preset to 2.93V, which is suitable for 3V-powered systems, ensuring compatibility without the need for external components.
• Low Power Consumption: With its low supply current of only 1.2µA, this device is an excellent choice for battery-operated systems where power efficiency is crucial.
• Manual Reset Input: An additional feature of this device is the manual reset input, which provides a means to initiate a system reset manually.
• Robust Operating Temperature Range: The device operates over an extended temperature range of -40°C to +85°C, making it suitable for use in a variety of environmental conditions.
• Immune to Short Vcc Transients: The MAX6316LUK29CY+T is designed to ignore fast transients on the Vcc line, preventing false resets and ensuring stable operation.

Applications:

The MAX6316LUK29CY+T is ideal for use in a range of applications that require reliable voltage monitoring and reset capabilities. These include:

• Portable/Battery-Powered Equipment
• Computers and Controllers
• Embedded Systems
• Industrial Controllers
• Intelligent Instruments

In conclusion, the MAX6316LUK29CY+T from Maxim Integrated is a robust and reliable solution for managing microprocessor resets, ensuring that digital systems maintain their integrity and reliability across a wide range of operating conditions and applications.
