The MAX6754UKZD0+T is part of the extensive selection of solid-state components available from Maxim Integrated. This Supervisory circuit from the Power Management Integrated Circuits (PMIC) series has been specifically designed to protect electronic systems from damage due to power failures, over-voltage conditions and other system faults. The MAX6754 is an economical, reliable solution for monitoring power system status and maintaining system integrity.

The MAX6754UKZD0+T can be used in a variety of application fields. Its primary use is in embedded and industrial control systems, such as those found in factory automation equipment, robotics, communication systems and medical monitoring devices. Additionally, it is suitable for automotive and protective applications, where multiple operating voltages must be monitored, high temperature ranges must be endured, and long-term reliability is desired. Furthermore, this device can also serve as a voltage detector where an alert or reset response is needed when the monitored voltage reaches a user-defined threshold.

The MAX6754UKZD0+T is a precision voltage supervisor that provides fast power fail detection, power-on reset (POR) generation, overvoltage protection (OVP) and low voltage detection (LVD). It features a high-precision 2.5V internal reference, support for external references, hysteresis to minimize unwanted system resets, adjustable warning (Warn) thresholds for early fault indication, and an overtemperature reset (OTR) feature.

The MAX6754UKDZO+T offers both automatic and manual reset capabilities. Automatic reset is initiated when the power fails or the monitored voltage drops below the reset (RST) threshold for a minimum amount of time. Manual reset is accomplished by supplying a logic level reset command. Both types of reset initiate a “power-on reset” (POR) pulse that resets the system microprocessor or controller after power is restored.

The OVP functionality of the MAX6754UKZD0+T takes over after VCC reaches the Overvoltage threshold. An OVP interrupt can be used to disconnect power to external loads or shut down noncritical circuits prior to destructive voltage levels. The LVD feature monitors the voltage of an external supply and provides a warning or reset output when the wattage drops below a user-specified threshold.

In addition, the MAX6754UKDZO+T has an overtemperature reset (OTR) feature that provides system protection from excessive ambient heat. An OTR reset can be triggered if the package temperature exceeds an internal temperature threshold. By providing protection from both temperature and voltage extremes, the MAX6754UKZD0+T helps extend the life of system components and furthers the reliability of the application.

In conclusion, the MAX6754UKZD0+T Supervisory circuit is an economical, reliable solution for monitoring power system status and maintaining system integrity in a variety of application fields. It offers both automatic and manual reset capabilities and provides protection from overvoltage, undervoltage and overtemperature conditions.
