Product Overview: MAX6315US44D3+T from Maxim Integrated

The MAX6315US44D3+T is a high-quality, precision microprocessor (µP) supervisory circuit produced by Maxim Integrated, a renowned leader in the development of innovative analog and mixed-signal products. This component is designed to monitor power supplies in µP and digital systems, providing a significant layer of protection by ensuring that the system operates within safe voltage levels.

With a fixed-sense threshold voltage of 4.40V, the MAX6315US44D3+T is particularly well-suited for 5V-powered systems. Its primary function is to assert a reset signal whenever the VCC supply voltage falls below the preset threshold, effectively resetting the µP. The reset signal is maintained for a minimum of 140ms after VCC has risen above the reset voltage threshold, ensuring that the system has stabilized before normal operation resumes.

One of the key features of this supervisory circuit is its low power consumption, with a typical supply current of only 1.2µA. This makes it an ideal choice for power-sensitive applications. Furthermore, the device is highly precise, with a threshold voltage tolerance of ±1.5% at room temperature, which increases the reliability of the system it monitors.

The MAX6315US44D3+T comes in a compact SOT-143 package, allowing for efficient use of board space in space-constrained applications. It is also characterized for operation over a wide temperature range of -40°C to +125°C, making it suitable for use in various environments and applications.

For ease of implementation, this supervisory circuit includes a debounced manual reset input. This allows users to manually trigger a reset, providing additional control over the system's operation. Additionally, it features an active-low reset output, which is compatible with most µP and digital systems.

Maxim Integrated's commitment to quality ensures that the MAX6315US44D3+T supervisory circuit is a reliable and efficient solution for maintaining system integrity through proper voltage monitoring and reset functions. Its small size, low power consumption, and precision voltage monitoring make it a versatile component for a wide range of applications.
