The MAX6316MUK46AY+T is a high-quality microprocessor (µP) supervisory circuit designed and manufactured by Maxim Integrated. It is engineered to monitor power supplies in µP and digital systems, providing a quick and reliable reset of the system during power-up, power-down, and brown-out conditions. The MAX6316 series is specifically tailored to maintain system integrity and prevent code execution errors during instances of unstable system voltages.

This device comes in a compact SOT-23 package, making it an ideal choice for space-constrained applications. It features a preset factory-trimmed reset threshold voltage of 4.63V, which is suitable for 5V-powered systems. The reset output is active-low and is guaranteed to be in the correct state for VCC down to 1V, ensuring that the connected µP or digital system is held in reset until the supply voltage reaches the stable operating level.

The MAX6316MUK46AY+T offers a robust set of features, including a low supply current of 1.6µA (typical), which makes it an energy-efficient solution for portable and battery-powered devices. The reset timeout period is fixed at 140ms (min), providing a sufficient delay to ensure system stability before normal operation commences. Additionally, the device is fully immune to short VCC transients, enhancing system reliability.

Maxim Integrated's commitment to quality is evident in the MAX6316MUK46AY+T, with its operating temperature range of -40°C to +125°C, allowing for deployment in environments with extreme temperature variations. Furthermore, the device is available in tape and reel packaging, denoted by the "+T" suffix, which facilitates automated assembly processes, making it well-suited for mass production requirements.

In summary, the MAX6316MUK46AY+T is a highly reliable and efficient solution for system reset needs. Its precision, low power consumption, and small footprint make it an excellent choice for designers looking to enhance the operational stability of their digital systems.
