The XC6118N36DGR-G is a form of PMIC (Power Management Integrated Circuit) that is categorized under the category of Supervisors. It is part of a long line of PMICs developed by Exar Corporation for fulfilling varying customer needs. The XC6118N36DGR-G belongs to the family of microcontroller-based supervisor circuits that are designed to provide overvoltage, overcurrent, and temperature protection for high-performance, cost-sensitive, microcontroller-based designs.

The microcontroller-based supervisor of XC6118N36DGR-G offers a wide range of functionalities in monitoring the supply voltage of systems. It includes an adjustable overvoltage protection, a programmable overcurrent protection, and a configurable over-power protection. It also comes with a temperature diode incorporated inside the package which is used to detect temperature changes and take preemptive action. The in-package temperature monitor can also be used to implement pre-defined fault conditions.

The XC6118N36DGR-G is tailored to be used in advanced power supply and voltage supervisor applications. It offers a wide operating supply voltage range of +3.3V – 28V and features an active-low reset output that is available for open-drain implementations. Package options include SOIC and DIP. Additionally, the XC6118N36DGR-G comes with the Exar PowerBench development system, which makes it suitable for systems applications where debugging or custom software development is necessary.

The working principle of XC6118N36DGR-G is to monitor the voltage supply, current, and temperature of the system. It utilizes an internal comparator circuit that compares the system supply voltage to an external reference voltage. If the voltage exceeds the set threshold, the output of the comparator will become active and will trigger a reset signal. When this happens, the reset output will then send a signal to the microcontroller to shut down the system and prevent any damage caused by the voltage spike.

The XC6118N36DGR-G also implements a built-in overcurrent protection system that uses a current sense circuit and an adjustable current-limit setting. The system will detect when the current load in the system is exceeding the set limits and trip the current limit output. The overcurrent protection feature is designed to protect the system from high current and thermal overloading, preventing any physical damage to the system. Furthermore, the XC6118N36DGR-G also provides in-package temperature monitor that allows the system to detect any rapid temperature changes in the system and prevent potential system damage caused by thermal issues.

In conclusion, the XC6118N36DGR-G offers a unique feature set of overvoltage, overcurrent, and temperature protection for high-performance and cost-sensitive designs. The microcontroller-based supervisor circuit of this device is the perfect choice for systems applications where the protection features are necessary. Its easy-to-use design and built-in features make it an ideal solution for protecting cost-sensitive applications from unexpected and undesired system failure.
