Maxim Integrated MAX6316LUK26DY-T Microprocessor Reset Circuit

The MAX6316LUK26DY-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 layer of protection by ensuring that the μP boots up in a predictable state every time the system is powered on. This component is essential for maintaining system integrity and preventing data corruption during power-up, power-down, and brown-out conditions.

Encased in a compact SOT-23 package, the MAX6316LUK26DY-T offers a combination of features that make it particularly suitable for portable and space-constrained applications. Its primary function is to assert a reset signal whenever the VCC supply voltage falls below the factory-set reset threshold level of 2.6V. The reset output remains asserted for a period of at least 140ms after VCC has risen above the reset threshold, ensuring a proper reset of the microprocessor during power-up.

The device boasts a low supply current of only 1.2μA, which is ideal for battery-operated equipment where power efficiency is crucial. Additionally, the MAX6316LUK26DY-T includes a debounced manual reset input, allowing for a system reset to be manually triggered when necessary.

Key features of the MAX6316LUK26DY-T include:

• Factory-Set Reset Threshold Voltage: 2.6V
• Guaranteed Reset Valid to VCC = 1V
• Low Power Consumption: 1.2μA Supply Current
• Minimum 140ms Reset Pulse Width
• Debounced Manual Reset Input
• Immune to Short VCC Transients
• Compact 5-Pin SOT-23 Package

With its precision voltage monitoring and low power consumption, the MAX6316LUK26DY-T is an excellent choice for managing system resets in microcontrollers, computers, controllers, intelligent instruments, and portable consumer electronics. Its robust design ensures that your system operates reliably across a variety of conditions and applications.

Overall, the MAX6316LUK26DY-T from Maxim Integrated stands out as a highly efficient and dependable solution for system monitoring and reset functions, providing peace of mind for designers and engineers looking to enhance the operational stability of their digital systems.
