Maxim Integrated MAX6314US25D4+T Microprocessor Reset Circuit

The MAX6314US25D4+T is a highly reliable microprocessor (μP) supervisory circuit designed to maintain system integrity during power fluctuations and failures. Manufactured by Maxim Integrated, a renowned leader in analog and mixed-signal engineering, this component is engineered to monitor power supplies in μP and digital systems, providing a robust layer of protection against unpredictable power conditions.

With a fixed-sense threshold voltage of 2.5V, the MAX6314US25D4+T is suitable for 2.5V-powered circuits, ensuring that systems operating at this voltage level remain within their safe operating parameters. This device delivers a precision voltage monitor and is equipped with a manual reset input, allowing for a controlled and user-initiated system reset, which is crucial for maintenance and troubleshooting procedures.

The MAX6314US25D4+T comes in a compact 4-pin SOT-143 package, making it ideal for space-constrained applications where board real estate is at a premium. Despite its small size, it does not compromise on performance, offering a low supply current of typically 1μA, which is highly beneficial for portable and battery-operated devices where power efficiency is paramount.

This supervisory circuit features an active-low reset output, which remains asserted for a minimum reset timeout period of 140ms after V_CC has risen above the reset threshold. This ensures that the μP has sufficient time to initialize and stabilize before commencing normal operations. The reset output is guaranteed to be in the correct state for V_CC down to 1V, providing additional reliability in low-voltage conditions.

Designed for high-precision applications, the MAX6314US25D4+T offers an impressive temperature range of -40°C to +85°C, allowing it to operate effectively in a wide range of environmental conditions. This makes it an excellent choice for automotive systems, industrial controls, embedded systems, and any other applications that require a high degree of reliability and stability.

In summary, the Maxim Integrated MAX6314US25D4+T is a robust and precise μP supervisory circuit that ensures system stability and integrity. Its low power consumption, compact form factor, and high precision make it an essential component for a myriad of electronic systems requiring consistent and reliable operation.
