Maxim Integrated MAX6314US25D4-T Microprocessor Reset Circuit

The MAX6314US25D4-T is a high-quality microprocessor (µP) supervisory circuit designed to monitor power supplies in µP and digital systems. It provides a significant level of system reliability and accuracy required in critical applications, ensuring that the µP resets to a known state during power-up, power-down, or brown-out conditions. Manufactured by Maxim Integrated, a leader in analog and mixed-signal products, this component is a testament to the company's commitment to providing robust and precision-engineered solutions.

This supervisory circuit operates with a nominal supply voltage of 2.5V, which is ideal for low voltage systems. It features an active-low RESET output, which remains asserted for a minimum of 140ms after VCC has risen above the reset threshold level, ensuring that the system has sufficient time to stabilize before the processor starts. The MAX6314US25D4-T comes in a compact, 4-pin SOT-143 package, making it suitable for space-constrained applications.

One of the key attributes of the MAX6314US25D4-T is its low supply current of 1.2µA (typical), which is particularly beneficial for battery-powered devices where power efficiency is crucial. Additionally, this device is characterized for operation over a wide temperature range of -40°C to +85°C, allowing it to perform reliably in various environmental conditions.

The device's robustness is further enhanced by its integrated glitch immunity, which ensures that the output remains in a reset state during transient conditions that momentarily dip below the reset threshold. This feature helps prevent erroneous operation of the µP during periods of unstable power.

For designers and engineers looking for a reliable reset circuit to maintain system integrity, the MAX6314US25D4-T from Maxim Integrated is an excellent choice. With its precision voltage monitoring, low power consumption, and compact form factor, it is well-suited for applications such as portable devices, embedded systems, and other digital equipment that require a high degree of system stability.

With the MAX6314US25D4-T, you can expect consistent performance and peace of mind, knowing that your system's processor will be operating within its intended parameters, even under adverse power conditions.
