PMIC - Supervisors are power management integrated circuits (ICs) used to control the power supply to a circuit or micro-controller. They often serve two purposes - to monitor the power supply for errors such as undervoltage, overvoltage, or over-temperature, and to provide an orderly startup sequence for the microcontroller and other devices that depend on the regulated power supply. The S-80849CLY-Z2-U is one such device that is often used to monitor, protect, and control the various power and voltage supplies in embedded systems.

The S-80849CLY-Z2-U is commonly used in applications such as industrial process control, automotive, aerospace, and embedded systems. It offers a wide range of system power protection and provides up to eight voltage/current supervision outputs and eight system interrupts. This makes it ideal for applications that require additional power management features and significantly reduces the design time for any embedded system.

When it comes to application fields, the S-80849CLY-Z2-U is mostly used in applications where the processor is the primary controller of the system. It is particularly suitable for microcontroller-based systems where the microcontroller is used to control the main system resources. This includes industrial control systems, automotive and aerospace applications, medical instrumentation, power management, and embedded microcontroller applications. The voltage/current supervision outputs can detect an undervoltage, overvoltage, and over-temperature conditions and provide a system reset, while the system interrupts can be used to activate any external circuit so as to allow a greater degree of system monitoring and control.

In terms of its working principle, the S-80849CLY-Z2-U monitors, protects, and controls system power mainly using its voltage/current supervision outputs and system interrupts. The onboard voltage regulator converts input voltages to the various internal power rails, while the system interrupt controller monitors and filters out any high-frequency noise on the power rails and then sends out an interrupt signal when any of the specified conditions have been met. The onboard high-side switch then disconnects the regulated power supply in case of an overvoltage or undervoltage condition. Special features such as over-temperature protection, on/off logic signals, and deadtime insertion are also provided.

Overall, the S-80849CLY-Z2-U is a highly versatile PMIC – Supervisors that can provide significant power management features and make embedded system design significantly faster and easier. It is commonly used in applications such as industrial process control, automotive, aerospace, and embedded systems, and is mainly controlled by its voltage/current supervision outputs and system interrupts. Thanks to its many features, it is highly suitable for prototyping and product development.
