The MAX6316LUK46BY+ is a highly reliable, low-power microprocessor (µP) supervisory circuit designed by Maxim Integrated 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 4.6V power supply voltage.

This device is specifically engineered to maintain system integrity by monitoring the power supply voltage. In the event of a power failure or an unexpected dip below the factory-set reset threshold, the MAX6316LUK46BY+ asserts a reset signal to prevent the µP from executing erroneous instructions. This reset signal remains asserted for a minimum of 140ms after the supply voltage exceeds the reset threshold, ensuring the system has stabilized before the processor begins operation. This feature is critical for applications where data integrity is paramount.

The MAX6316LUK46BY+ comes in a compact SOT-23 package, making it suitable for space-constrained applications. It is characterized for operation over a wide temperature range of -40°C to +85°C, which allows for its use in diverse environmental conditions. The device's low supply current of 1.2µA (typ) makes it ideal for portable and battery-operated equipment.

Additional features of the MAX6316LUK46BY+ include a debounced manual reset input, which enables a manual override of the automatic reset, providing designers with greater control over the reset logic. This manual reset can be triggered with a simple push-button or logic signal, making it user-friendly and versatile for different reset activation scenarios.

In summary, the MAX6316LUK46BY+ from Maxim Integrated is a robust and reliable solution for system reset management. Its precision monitoring of the supply voltage, along with its ease of integration due to the lack of external components, makes it a popular choice among engineers for maintaining system integrity across a variety of electronic applications.
