Power management integrated circuits (PMIC) are electronic devices that allow for energy efficiency by regulating power in electronic systems. PMICs offer a versatile platform for powering and protecting designs by leveraging switching regulators, linear regulators, hot swap controllers and multiplexers. Supervisors are specialized ICs that provide system reset, monitor supply voltages and monitor overall system health. As the complexity of power topologies continues to increase, new solutions are needed to ensure system health and stability. PMICs like the MAX6865UK31D4S+T provide the most advanced supervisor solutions, making them ideal for a wide range of applications.

The MAX6865UK31D4S+T is a semicustom PMIC configured with 7 optimized regulators. It integrates a 5V/3V reset IC, two 400mA linear regulators, two controllers/hot swap controllers, and two multiplexers, as well as additional features tailored to specific customers. Its many features include adjustable, programmable output voltage, digital control, and protection against negative voltage and over- or undervoltage conditions. The IC also includes a voltage supervisor, which ensures power supply stability and prevents the system from becoming unstable in the event of an unexpected power failure.

The MAX6865UK31D4S+T’s integrated digital internal voltage supervisor (DVLS) can trigger an adjustable digital reset (DRST) signal for any monitored voltage-level faults, including both over- and undervoltage conditions. It also provides a selectable and adjustable analog reset output voltage at thresholds of 0.3V, 1.25V, 1.6V, 1.9V, and 3.0V, with a 3 dB bandwidth above and below the reference voltage of 5V±1%. The voltage supervisor can also output multiple reset and monitoring signals that are free of noise and interference.

The MAX6865UK31D4S+T is ideal for a wide range of applications that require robust power management, such as industrial and consumer equipment. It is ideal for wearable and other low-power portable designs, as they are designed to run on a single battery or a combination of secondary cells, and the supervisor ensures system stability even when these sources are unstable. This feature is also useful for automotive systems, which require high levels of stability and diagnostic capabilities in their onboard systems. The digital control of the MAX6865UK31D4S+T also makes it well-suited for aerospace and military applications, as it can handle multiple power rails and withstand extreme temperatures, vibrations, and shock.

In conclusion, energy efficiency is key in today’s electronic systems, and PMICs offer a wide range of solutions for regulating power. The MAX6865UK31D4S+T is an ideal solution for applications requiring advanced supervisor technologies. Thanks to its powerful voltage supervisor and wide range of features, it is well-suited for industrial and consumer equipment, wearable technology, automotive applications, and aerospace and military projects.
