The XC6120N322HR-G supervisory circuit is a low-power, high-performance and mixed-signal voltage regulator which belongs to the PMIC (Power Management Integrated Circuit) family. It is designed for the purpose of monitoring auxiliary power supply rails and detecting power changes on the system main power rail. This device can be used in a wide range of applications, from digital peripherals and systems to mixed-signal microcontrollers and FPGA applications.

The XC6120N322HR-G is a high level of functionality integrated device ideal for monitoring and protecting high-value digital systems. It has a low-power design architecture, and specialized protection features such as overvoltage and brownout protection.

The XC6120N322HR-G integrates a precision voltage detector and has a wide range of accuracy settings with excellent accuracy. It has a high detection accuracy and can be used to detect power on/off events from the main power rail. The device also comes with a microcontroller reset function and a Watch Dog Timer (WDT) feature which can be easily enabled from software.

The XC6120N322HR-G has a wide array of features designed for use in embedded systems, such as excellent overvoltage, reset and back driving protection, a digital control/status interface, a high-speed analog comparator, and a low-power digital control circuit.

The XC6120N322HR-G working principle is to detect voltage inputs in the range of 1.2V to 5.5V, and convert it to a logic level high or low signal, based on the voltage detection level settings in the device. The device is equipped with two delay timers, one to measure the voltage drop below the threshold, the other to mark the time the main power rail stays below the threshold. The delayed time and the trip time can be set at different intervals, to provide a wide range of protection from sudden power fluctuations.

The device also features a Watch Dog Timer (WDT) feature which can be enabled from software. The WDT allows for resetting the system in case of an unexpected power off, by issuing a software-controlled reset. It also boasts a digital control/status interface which can be used for monitoring the output voltages and controlling the device settings, as well as an analog comparator to sense power related events.
