Maxim Integrated MAX6316LUK46BX Microprocessor Reset Circuit

The MAX6316LUK46BX is a highly compact, 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 with 5V-powered circuits.

This supervisory circuit from Maxim Integrated ensures that the µP is reset to a known state during power-up, power-down, or brown-out conditions. It features a factory-trimmed reset threshold suitable for operation with a 4.6V power supply, ensuring that systems with a 5V nominal supply have a sufficient margin to maintain stability and proper operation.

The MAX6316LUK46BX boasts an impressive feature set tailored for robust system control:

• Precision Monitoring: It has a precision voltage monitoring capability, ensuring that the reset output is issued whenever the supply voltage falls below the 4.6V threshold.
• Manual Reset Input: A manual reset input is provided, allowing for a reset to be triggered with an external signal, adding an extra layer of control for system operators or during debugging processes.
• Low Power Consumption: The device's low power consumption makes it an ideal choice for portable and battery-operated applications.
• High Reset Valid to VCC: The reset output remains valid with VCC as low as 1V, ensuring reliable system reset even during low power conditions.
• Immune to Short VCC Transients: Fast transients on the VCC line are filtered, preventing false resets and improving system stability.
• Compact SOT-23 Packaging: The small, 5-pin SOT-23 package is space-saving, making it suitable for use in systems where board space is at a premium.

Applications for the MAX6316LUK46BX include portable devices, computers, controllers, and intelligent instruments, where consistent and reliable operation is critical. Its integration into a system design helps to protect the integrity of the µP and associated components by ensuring that the system operates within its voltage parameters, thus preventing data corruption and hardware damage.

By choosing the MAX6316LUK46BX for your design, you are selecting a product from Maxim Integrated that is synonymous with quality, reliability, and precision in voltage monitoring and system reset functions.
